A solution of tpp (0.050 mmol, 0.020 g; Goodwin & Lions, 1959) and cis-PtCl2(DMSO)2 (0.10 mmol, 0.042 g; Price et al., 1972) in methanol (15 ml) was reacted within a pressure-resistant sealed tube at 393 K for 12 h. After the solution was cooled down to room temperature, orange prisms of (I) were collected by filtration.
All H atoms were located at their idealized positions as riding atoms (C—H = 0.96 Å for the methyl protons of DMSO and C—H = 0.93 Å for the aromatic protons of tpp). In the final difference Fourier synthesis, 33 residual peaks in the range 1.0–1.55 e Å−3 were observed within ca 1.3 Å of the Pt atoms. Initially, data were collected to θmax of 27.5°, but upon inspection, the data above θmax of 23.3° were essentially unobserved. The the data above 23.3° were discarded for the refinement of the structure. This resulted in 57% of the unique data being having I > 2σ(I).

Experimental. The first 50 frames were rescanned at the end of data collection to evaluate any possible decay phenomenon. Since it was judged to be negligible, no decay correction was applied to the data. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Attempts have been made thus far to develop new types of one-dimensional platinum compounds in our laboratory (Sakai et al., 2002). We were hoping to obtain systems involving relatively large aromatic systems and recently started exploring the coordination chemistry of platinum and 2,3,5,6-tetrakis(2-pyridyl)pyrazine (tpp). The title compound was obtained during efforts to synthesize tetravalent dimer cations of hexadentate tpp, such as [Pt2(NH3)2(µ-tpp)]4+, even though the preparation of such compounds have been unsuccessful so far. Here we report on the crystal structure of an unprecedented double salt obtained for the Pt-tpp family, [Pt2Cl2(µ-tpp)][PtCl3(DMSO)]2, (I).
Up until now, at least 34 tpp complexes have been structurally analyzed by X-ray diffraction (see CCDC), and at least eight kinds of coordination modes have been characterized. These compounds involve mono-, di-, and trinuclear complexes, but there have been no structures of mixed-metal complexes determined. Among them, 12 complexes possess a structure in which tpp bridges two metal centers with two tridentate moieties in a mer fashion. As for Pt, only one compound, namely [Pt2(PEt3)2Cl2(µ-tpp)][Pt(SnCl3)4(PEt3)] (Teles et al., 2000), has been structurally characterized, where tpp binds to two Pt atoms with two bidentate moieties while the two N donors of the pyrazine ring do not take part in the coordination. In this context, this is the first example of a Pt–tpp complex in which tpp bridges two Pt centers in a fully ligated form with two chelates in a mer fashion.
As shown in Fig. 1, a dinuclear cation and two mononuclear anions are found in the asymmetric unit of (I). Displacement parameters of DMSO C and O atoms are relatively large, reflecting the rotational flexibility about the Pt—S axes. The tpp ligand is largely distorted from the planarity in order to avoid the steric contacts between the protons at the 3-position of pyridyl moieties. The twist originated at the tpp ligand is estimated to be ω(tpp) = 26.7 (2)° based on the best-plane calculations performed for two halves of the ligand (see Fig. 2), where 15-atom r.m.s. deviations are 0.102 and 0.117 Å. The twist angle estimated based on the dihedral cant between two Pt coordination planes is ω(Pt1/Pt2) = 19.6 (9)°, where four-atom r.m.s. deviations are 0.008 and 0.014 Å. These values are quite similar to those reported for [Pd2(NO3)2(µ-tpp)](NO3)2·0.5H2O [ω(tpp) = 29.1° and ω(Pd1/Pd2) = 21.9°; Yamada et al., 2000]. On the other hand, Ni complexes are reported to have relatively large twists compared to those discussed above [ω(tpp) = 38.3° and ω(Ni1/Ni2) = 31.9° for [Ni2(acetato)4(H2O)2(µ-tpp)]·CH2O (Koman et al., 1998), and ω(tpp) = 34.6° and ω(Ni1/Ni2) = 25.1° for [Ni2(H2O)6(µ-tpp)](NO3)4·2.5H2O (Graf et al., 1997)].
Shifts of Pt1 and Pt2 atoms from their coordination planes are estimated as 0.020 and 0.003 Å, respectively. The former is clearly relevant to the effective d–π interaction achieved between the Pt atom and the neighbouring tpp moiety [Pt1—C24ii = 3.40 (3) Å; symmetry code: (ii) −x, 1 − y, 1 − z]. However, face-to-face interactions between the tpp ligands appear to dominate the stabilization of crystal packing of (I). The intermolecular Pt···Pt distances listed in Table 1 indicate that Pt···Pt interactions are not enhanced in this system.
Finally, it should be noted that the Pt—Cl distances within the dimer unit [2.278 (7) and 2.268 (7) Å] are effectively shorter than those in [PtCl3(DMSO)]− [2.294 (8)–2.320 (7) Å], presumably due to the relatively strong back-donation promoted by the tpp ligand.
