In the title compound, [Sn(CH3)3(C7H7N2O2S)(H2O)], the SnIV atom has a distorted trigonal–bipyramidal coordination geometry, with one carboxyl­ate O atom of the 2-(4-methyl­pyrimidine-2-sulfan­yl)acetate ligand and the O atom of a water mol­ecule in axial positions, and three methyl groups in equatorial positions. In the crystal, mol­ecules are linked via O—H⋯O and O—H⋯N hydrogen bonds, forming double-stranded chains propagating along [010].

Comment top

The title compound is a trimethyltin ester of 4-methylpyrimidine-2-thioglycolic acid, Fig. 1. The geometry of tin atom, Sn1, is a slightly distorted trigonal bipyramid, surrounded axially by atom O2 of the ligand and atom O3 of a water molecule. The axial angle O2—Sn1—O3 is 176.66 (16) Å close to a linear arrangement. Three carbon atoms of the methyl groups are located in the equatorially plane and the sum of the trigonal C—Sn—C angles is 358.1°, which illustrates that the three methyl C atoms and the tin atom are nearly coplanar. The Sn—O distances of 2.144 (4) Å and 2.488 (5) Å, are a little longer than the covalent bond length of tin and oxygen (Zhang et al., 2007) but similar to the same distances reported for other triorganotin polymeric structures (Zhu et al., 2011).

In the crystal, molecules are linked via O-H···O and O-H···N hydrogen bonds forming double-stranded chains propagating along [010]; see Table 1 and Fig. 2.

Experimental top

The reaction was carried out under an atmosphere of nitrogen. 4-methylpyrimidine-2-thioglycolic acid (1 mmol) and sodium ethanol (1 mmol) were added to a stirred solution of ethanol (30 ml) in a Schlenk flask and stirred for 30 min. Trimethyltin chloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 12 h at 353 K. The resulting clear solution was evaporated under vacuum. The product was crystallized from dichloromethane to yield colourless block-like crystals of the title compound [Yield 80%; M.p. 430 K]. Anal.

Refinement top

The water molecule H atoms were placed in calculated positions and treated as riding atoms: O-H = 0.85 Å with Uiso(H) = 1.5Ueq(O). The C-bound H atoms were also placed in calculated positions and treated as riding atoms: C—H = 0.93 and 0.96 Å, for CH and CH3 H atoms, respectively, with Uiso(H) = 1.5Ueq(C-methyl) and = 1.2Ueq(C) for other H atoms. In the final cycles of refinement two reflections were omitted as (Iobs-Icalc)/ΣW > 10.

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 esds 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 > 2sigma(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.
