Abstract top

In the title compound, [Sn(C6H5)3(C2H3OS2)], the SnIV atom adopts a distorted SnC3S tetrahedral coordination geometry. A short Sn...O contact [2.988 (4) Å] is also present. The phenyl rings are each disordered over two sets of sites with an occupancy ratio of 0.550 (8):0.450 (8). The crystal studied was found to be a racemic twin with a twin component ratio of 0.57 (18):0.43 (18).

Comment top

The crystal structure of (O-methyl dithiocarbonato-S)-triphenyl-tin(iv) (Ng & Rae, 2000) has been reported, which is related to title compound (I).

In (I) the coordination around tin atom is distorted tetrahedral with three C-atoms and an S-atom. The tin and coordinated sulpher atom is at a distance of -0.5497 (47) Å and -2.9805 (53) Å from the plane (C3A/C9A/C15A). The phenyl rings are disordered over two sites with occupancy ratio of 0.550 (8):0.450 (8). The dihedral angle between disordered rings (C3A–C8A)/(C3B–C8B), (C9A–C14A)/(C9B–C14B) and (C15A–C20A)/(C15B–C20B) is 19.2 (7)°, 8.3 (10)° and 14.1 (5)°, respectively. The O-methyl hydrogen carbonodithioate moiety (S1/C1/S2/O1/C2) is planar with r. m. s. deviation of 0.0326 Å and is oriented at a dihedral angle of 71.22 (19)° with the plane (C3A/C9A/C15A).

Experimental top

Potassium-O-methyl carrbonodithioate (10 mmol, 1.46 g) was dissolved in methanol and stirred for 30 min. Then triphenytin(IV) chloride was added dropwise and the reaction mixture was stirred for 7–8 h till white precipitates were appeared. The resultant mixture was filtered to remove KCl salt. The filtrate was rotary evaporated to get white solid mass and recrystalized from chloroform to obtaine colourless prisms of (I) in 85.33% yield.

Refinement top

There is a recamic twin with BASF value of 0.43147.

The benzene rings of triphenyl tin are disordered over two sites with occupancy ratio of 0.550 (8):0.450 (8) and were idealized as regular hexagons with C–C bond distance equal to 1.39 Å. The C-atoms of respective rings were treated as anisotropic with equal thermal parameters.

The H-atoms were positioned geometrically (C–H = 0.93–0.96 Å) and refined as riding with Uiso(H) = xUeq(C), where x = 1.5 for methyl and x = 1.2 for other H-atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
