Abstract top

The title compound, [Sn(C4H9)2(C5H8NS2)Cl], contains two molecules in the asymmetric unit, with similar conformations. In both molecules, the Sn atom adopts a distorted trigonal-bipyramidal geometry arising from two C atoms, one Cl atom and two S atoms from the bidentate dithiocarbamate ligand, with one Sn-S bond much longer than the other. One C atom of the pyrrolidine ring is disordered equally over two sites.

Comment top

Chlorodialkyltin(IV) derivatives of monobasic chelating ligands generally exist as six-coordinate compounds arising from chloride-ion bridging (Ng et al., 1989). An example of such a compound is chloride-bridged, dimeric chlorodimethyl(N,N-dimethyldithiocarbamato)tin, whose crystal structure has been known for a long time (Furue et al., 1970). Replacing the methyl group on tin by the phenyl group interferes with the bridging, as noted in chlorobis(N-cyclohexyl-N-ethyldithiocarbamato)diphenyltin (Hall & Tiekink, 1995).

The sterically bulky t-butyl group in the title compound, (I), is also expected to disrupt bridging, and a molecular species results (Fig. 1). There are two molecules in the asymmetric unit, with similar geometries. In both cases, the tin(IV) atom adopts a distorted C2ClS2Sn-trigonal bipyramidal geometry (Table 1). The formally double-bonded sulfur atom occupies one of the apical sites and the chloride ion the other in the axially most-electronegative configuration. Othwerwise, the geometrical parameters for (I) may be regarded as normal (Allen et al., 1987) and are similar to those found in the other R2ClSnS2CNR'2 mentioned above.

Experimental top

The title compound was synthesized by the method described in the literature (Jung & Sohn, 1988). Recrystallization from a 1:1 v/v mixture of dichloromethane-hexane yielded colourless blocks of (I). M.P. 439 K. Analysis. Calc. for C26H52N2S4ClSn2: C 37.66, H 6.32; N 3.38%. Found: C 34.43, H 6.18, N 3.52%.

Refinement top

Some of the carbon atoms of the t-butyl groups show significant anisotropic displacements. Attempts to model this as disorder over two or more sites were not successful. Atom C4 is disordered over two positions in a 0.50 (3):0.50 (3) ratio.

The hydrogen atoms were geometrically placed (C–H = 0.96–0.97 Å), and refined as riding with U(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). The methyl groups were allowed to rotate, but not to tip, to best fit the electron density.

Special details top

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.
