Aqua-trimeth-yl[2-(4-methyl-pyrimidin-2-ylsulfan-yl)acetato-κO]tin(IV).

In the title compound, [Sn(CH3)3(C7H7N2O2S)(H2O)], the Sn(IV) atom has a distorted trigonal-bipyramidal coordination geometry, with one carboxyl-ate O atom of the 2-(4-methyl-pyrimidine-2-sulfan-yl)acetate ligand and the O atom of a water mol-ecule in axial positions, and three methyl groups in equatorial positions. In the crystal, mol-ecules are linked via O-H⋯O and O-H⋯N hydrogen bonds, forming double-stranded chains propagating along [010].
