The title compound, K2[SnCl3]Cl·H2O, is the prototype of some isostructural compounds of composition M2[SnX3]X·H2O (M = large monovalent cation; X = halogen). In comparison with a previous study based on photographic data [Kamenar & Grdenić (1962[Kamenar, B. & Grdenić, D. (1962). J. Inorg. Nucl. Chem. 24, 1039-1045.]). J. Inorg. Nucl. Chem. 24, 1039–1045], its crystal structure has now been redetermined using CCD-based data in order to gain more accurate values for bond lengths and angles within the [SnCl3] anion and to locate the H atoms. The [SnCl3] anion has a trigonal–pyramidal shape and exhibits crystallographic mirror symmetry. With the exception of the K+ ion which is located on a general position, all other atoms are situated on crystallographic mirror planes. The coordination polyhedron of the cation may be described by means of nine atoms in the form of a monocapped square anti­prism with seven typical K—Cl/O distances and two additional atoms at considerably longer distances. The positions of the H atoms of the water mol­ecule (also lying on a crystallographic mirror plane) could be determined and confirm the existence of a bifurcated O—H⋯Cl hydrogen bond to neighbouring Cl atoms.

Comment top

The title compound came into the focus of our interest when we became aware that it represents the prototype of a series of isostructural compounds of composition M2[SnX3]X.H2O with M = K, Rb, NH4; X = Cl, Br, containing a trigonal-pyramidal [SnCl3]- ion with crystallographic mirror symmetry that is only slightly distorted by weak secondary interactions of the tin(II) atom by more remote neighbouring chlorine atoms. Unfortunately, the precision of bonds lengths and angles available from the literature suffer from the fact that the crystal structure has been determined from two sets of Weissenberg photographs covering only 178 reflections with hk0 and 0kl (Kamenar & Grdenić, 1962). To get more precise and accurate information, we decided to reinvestigate the crystal structure at a temperature of 100 K to 2θ = 60°. Moreover, we intended to determine the position of the hydrogen atoms in order to confirm an older assumption on a bifurcated hydrogen bond derived from IR data (Falk et al., 1974).

The asymmetric unit of K2[SnCl3]Cl.H2O consists of half a formula unit, with one potassium ion in a general position, half a [SnCl3]- ion (with one chlorine atom in a general position and the tin atom as well as a second chlorine atom on the mirror plane), as well as a water molecule and third chlorine atom also located on a mirror plane.

As a result of its m symmetry, two of the three bond lengths and bond angles within the [SnCl3]- anion are equal (Tab. 1). The two different Sn—Cl bonds are very similar and differ by only 0.028 Å [mean value: 2.584 (17) Å]. All bond angles are significantly smaller than 90° and very similar, too, the difference being 0.57° [mean value: 87.6 (3)°]. All in all, deviations from higher point group symmetry 3m are very small. The coordination sphere of the tin atom is augmented by three additional chlorine atoms at more remote distances of 3.2854 (4) Å (Cl2) and 3.1311 (5) Å (Cl3, 2x). The interaction must be contributed mainly to electrovalent (ionic) forces although it is worthwhile to see that the shorter distance is opposite to the longest (Cl1) of the two covalent Sn—Cl bonds. In summary, this sixfold coordination gives rise to a strongly distorted octahedral arrangement (Fig. 1).

The potassium ion is surrounded in form of a distorted pentagonal biypramid from 6 chlorine atoms [2 x Cl1, 2 x Cl2, 2 x Cl3] with K—Cl distances in a very narrow range of 0.09 Å [3.1364 (4) - 3.2475 (4) Å, mean value: 3.21 (4) Å] and the oxygen atom of a water molecule in a distance of 2.7960 (10) Å. On the background that Cl1 and Cl2 are covalently bonded to tin it is interesting to see that the two shortest K—Cl distances [3.1364 (4) and 3.1948 (5) Å] are those to the isolated chlorine atom Cl3. The potassium coordination sphere is completed by an additional chlorine atom at a considerable longer distance of 3.7935 (5) Å (Cl3), and an additional oxygen atom of a second water molecule at a distance of 3.908 (1) Å. Taking these additional atoms into account, the coordination polyhedron of the potassium ion is best described as a distorted monocapped square antiprism (Fig. 2).

Since we could determine the position of both hydrogen atoms of the water molecule we were also able to confirm a former assumption on the existence of a bifurcated hydrogen bond of one hydrogen atom to two neighbouring chlorine atoms (Fig. 3). All three atoms of the the water molecule lie on a crystallographic mirror plane. Thus, the oxygen atom is coordinated to two potassium ions (µ2-O) outside the mirror plane with two equal distances of 2.7960 (10) Å, the angle between the potassium ions being 97.99 (5)°. One hydrogen atom (H1) forms a normal hydrogen bond to one chlorine atom (Cl3), also situated on the mirror plane, whereas the other one (H2) forms a bifurcated hydrogen bridge to two chlorine atoms (Cl2) outside the mirror plane, the latter being significantly weaker (longer) than the first one (Tab. 2), with both chlorine atoms enclosing an angle of 86.65 (1)° at this hydrogen atom.

The coordination sphere of the chlorine atom not covalently bonded to tin (Cl3), consists (Fig. 4) of four potassium ions in a somewhat distorted square planar arrangement [bond angles: 1 x 82.67 (1)°, 2 x 87.78 (1)°, 1 x 101.48 (1)°, bond lengths: 2 x 3.1948 (5), 2 x 3.1364 (4) Å] with one additional hydrogen atom (H1) to which it forms a hydrogen bond above the potassium plane. The position of this hydrogen atom is not exactly above the chlorine atom but shifted towards the side of the largest K—Cl—K angle.

In the solid (Fig. 5), the arrangement of all components (K+, Cl-, [SnCl3]-, H2O) is mainly dominated by electrovalent interactions and weak hydrogen bonds to the chlorine atoms as described above. Because various atoms (Sn, 2 x Cl, H2O) are situated on crystallographic mirror planes, the packing suggest the existence of a layer structure held together through the K+ ions between the layers. However, between the building units within the mirror plane there are similar weak interactions as between them and the interlayer atoms.

Experimental top

Colourless, needle-like single crystals of the title compound were prepared on a petri dish within some minutes by adding some drops of an aqueous solution of KCl to solid SnCl2.

Refinement top

Our low temperature measurement confirms the formerly determined orthorhombic unit cell but resulted in a smaller unit cell volume at T = 100 K. From systematical absences, space group Pnma, the standard setting of space group no 62, was derived. In the original study by Kamenar & Grdenić (1962) the non-standard setting of Pbnm was used.

Hydrogen atoms were clearly identified in difference Fourier syntheses. Their positions were refined with respect to a common O—H distance of 0.96 Å and an H—O—H bond angle of 104.9° before they were fixed and allowed to ride on the corresponding oxygen atoms. One common isotropic displacement parameter was refined for both H-atoms.

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.
