In the title salts, C12H14N22+·2ClO4, (I), and C12H14N22+·S2O82−, (II), the dication is organized around an inversion centre located at the centre of the –CH2CH2– bridge and the two pyridine segments are anti with respect to one another. The peroxo­di­sulfate anion in (II) also exhibits inversion symmetry. Hirshfeld surface analysis shows closely similar Hirshfeld surface shapes for the dications in the two salts, reflecting similar inter­molecular contacts and similar conformations. The two-dimensional fingerprint plots (FPs) are quite asymmetric, due to the presence of more than one component (cation and anion). The most striking of the complementary features for each of the FPs of the dications is the broad green spike in the region de > di, without the presence of a cor­res­ponding spike in the region de < di, reflecting the absence of O...H contacts. Moreover, H...O inter­actions (51% in the dications of both salts) outnumber other contacts in both crystal structures.

Introduction top

Hirshfeld surface analysis is a very useful tool for the investigation of inter­molecular inter­actions in crystal structures, allowing easy comparison of inter­molecular contacts relative to van der Waals radii by a strategy based on a simple colouring scheme (Rohl et al., 2008; Tarahhomi et al., 2013). Such an analysis may be used in the case of symmetry-independent molecules within one structure, analogous structures, cation–anion compounds and polymorphs (Tarahhomi et al., 2013; Ling et al., 2010).

When comparing the crystal structures of cation–anion compounds with one identical component (cation or anion), Hirshfeld surfaces (HSs; Spackman & Byrom, 1997; Spackman & Jayatilaka, 2009; McKinnon et al., 2004) and fingerprint plots (FPs; Spackman & McKinnon, 2002; McKinnon et al., 2004) may be used for elucidating and comparing the inter­molecular inter­actions involved in the crystal packing.

In organic synthesis, some cation–anion compounds based on organic cations and oxidant anions can be employed to improve the selectivity, the mildness and, therefore, the effectiveness of the oxidant species, especially in the oxidation of complex and highly sensitive compounds (Bobbitt, 1998). There are some reported structures of such cation–anion compounds, for example, the 1,1'-(ethane-1,2-diyl)dipyridinium dication with dichromate(VI) (Gholizadeh et al., 2012) and iodate anions (Gholizadeh et al., 2011).

Here, we present the syntheses and crystal structures of two new salts of the 1,1'-(ethane-1,2-diyl)dipyridinium dication, namely the bis­(diperchlorate) salt, (I), and the hexaoxo-µ-peroxo-di­sulfate­(2-) (also known as peroxodi­sulfate) salt, (II). Furthermore, Hirshfeld surface analysis, using the CrystalExplorer software (Wolff et al., 2012), was used to investigate and compare the inter­molecular inter­actions, viz. the H···H, H···O, H···C and C···H contacts, in (I) and (II).

Experimental top

Synthesis and crystallization top

(C14H18N2)Br2 was prepared as described previously (Gholizadeh et al., 2011). The preparation of both (I) and (II) is identical, with the exception of the salts used for providing the counter-anions. To a solution of (C14H18N2)Br2 (10 mmol) in water (25 ml), an aqueous solution (25 ml) of KClO4 (20 mmol) for (I), or a solution of K2S2O8 (10 mmol) for (II), was added and the resulting solution stirred at room temperature. For both compounds, after 1 h, the precipitate was filtered off, washed with water and recrystallized from H2O–di­methyl­formamide (1:1 v/v) at room temperature.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. For (I) and (II), all H atoms were placed in calculated positions, with C—H = 0.96 Å (aromatic and CH2) and Uiso(H) = 1.2Ueq(C). The data-reduction program CrysAlis PRO (Agilent, 2010) discarded two low-angle reflections [001 for (I) and 100 for (II)]. They were recorded in positions close to the beam stop or the Lorentz area of the CCD detector.

Results and discussion top

In the title bis­(diperchlorate), (I) (Fig. 1), and peroxodi­sulfate, (II) (Fig. 2), salts, the dications are organized around an inversion centre located at the centre of the –CH2CH2– bridge and the two pyridine segments are anti with respect to one another. The pyridinium rings are parallel in both cases, but the perpendicular distances between their planes are 1.486 (2) Å for (I) and 1.309 (4) Å for (II). This difference in the perpendicular distances of (I) and (II) is related to the difference in the angle between the plane of the pyridinium ring and the plane defined by atoms N2/C1/C1i/Ni for (I) [symmetry code: (i) -x, -y + 1, -z] and N2/C1/C1ii/Nii for (II) [symmetry code: (ii) -x + 1, -y + 1, -z]. The angle between the planes of the rings of 83.76 (15)° in (I) is closer to 90° than that of 73.88 (14)° in (II), thus allowing for a larger separation of the pyridinium rings. The peroxodi­sulfate anion in (II) also exhibits inversion symmetry. The Cl atom in (I) and the S atom in (II) are in tetra­hedral environments. Selected bond lengths and angles for (I) and (II) are given in Tables 2 and 4, respectively. The crystal packing of both structures are stabilized by C—H···O hydrogen bonds (Tables 3 and 5).

For the dications of (I) and (II), the three-dimensional Hirshfeld surface (HS) maps are given in Fig. 3; contacts with distances equal to the sum of the van der Waals radii are shown in white, and contacts with distances shorter than or longer than the related sum values are shown in red (highlight contacts) or blue, respectively. Tables 3 and 5 list the short inter­molecular contacts with distances shorter than the sum of van der Waals radii, and these are identified with red spots on the HSs and labels as defined in Fig. 3. The shapes of the HSs of the dications in both structures are similar, reflecting similar inter­molecular contacts (Tables 3 and 5) and similar conformations.

In the crystal packing, the dication of (I) takes part in different inter­molecular contacts, viz. C—H···O (labels 16, 9 and 11 in Fig. 3), C···O (label 7), C···C (labels 10 and 12) and N···O (label 8), and the dication of (II) is involved in inter­molecular C—H···O inter­actions (all labels except 7) and N···O (label 7) contacts. In both structures, each dication participates in some similar C—H···O hydrogen bonds, labelled in Fig. 3 as 2, 3, 5, 6 and 9 (Tables 3 and 5). The dark-red spots are related to the shorter C—H···O hydrogen bonds for both structures, and also to the unique Csp2···O inter­action for (I). The light-red spots on the HSs include other inter­molecular inter­actions (Fig. 3, and Tables 3 and 5).

Fig. 4 illustrates the analysis of the two-dimensional fingerprint plots (FPs) for the dications of (I) and (II). FPs are the two-dimensional representations of the information provided by visual inspection of the HSs, in which the distances of the nearest atoms outside, de, and inside, di, from the related HSs are plotted for evenly spaced points on the HSs. For a better identification of different H···X or X···H (X = H, O or C) contacts, the FP of each dication in (I) and (II) is decomposed into H···X-inter­actions-only fingerprints.

The two-dimensional fingerprint plots in Fig. 4 are quite asymmetric; this is expected, since inter­actions occur between two different species (cation and anion). In other words, the asymmetry about the plot diagonal is typical of structures that contain more than one component (molecule/ion) (Fabbiani et al., 2011).

In FPs of cation–anion compounds, the contact regions between the HSs of the two species (cation and anion) in the asymmetric unit are visible, and it is possible to identify complementary regions in the FPs, where one component (cation) acts as an H-atom donor (de > di) and the other as an acceptor (de < di). The most striking of these complementary features is the broad green spike in the region de > di on each of the full plots, resulting from the H···O contacts; similar spikes are not visible in the region de < di, due to the absence of O···H contacts. Moreover, the FPs in Fig. 4 clearly show the similarities, as well as the minor differences, between the distributions of inter­actions of the dications in (I) and (II).

Fig. 5 shows the relative contributions of the H···H, H···O, H···C and C···H contacts to the HS areas for the respective dications. By comparing the results in Fig. 5, it is seen that the H···O inter­actions outnumber the other contacts in the crystal structures (versus 0% area for the O···H inter­actions). Moreover, the percentages of the areas in Fig. 5 reveal that there are minor differences in the distribution of H···H and C···H inter­actions for the dications of (I) and (II).
