Di-μ-hydroxido-bis-[iodido-diphenyl-tin(IV)]-1,3-di-methyl-imidazolidin-2-one (1/2).

The title compound, di-μ-hydroxido-bis-[iodido-diphenyl-tin(IV)]-1,3-di-methyl-imidazolidin-2-one (1/2), [Sn(CH)I(OH)]·2CHNO, represents only the second example in the dimeric diorganotin(IV)-hydroxide-halide solvates [ Sn(OH)]·2 with = I. As is usual for this class of compound, dimerization takes place the oxygen atoms of the hydroxyl groups and leads to a planar, centrosymmetric, four-membered Sn-O ring of rhomboidal shape whose Sn-O distances [2.024 (2)/2.174 (2) Å] are determined by the position ( or ) of the oxygen atom on the respective trigonal-pyramidal coordinated tin atom while the bond angles are acute [70.74 (8)°] at the tin atoms and obtuse [109.26 (8)°] at the oxygen atoms.
