In the solid, state diphenyltin(IV)-hydroxide-iodide-N,N′-dimethylpropylene-urea, Ph2Sn(OH) ·DMPU, consists of centrosymmetric dimers exhibiting the characteristic structural features of diorganotin(IV)-hydroxide-halides.
The title compound, di-μ-hydroxido-bis[iodidodiphenyltin(IV)]–1,3-dimethylimidazolidin-2-one (1/2), [Sn(C6H5)2I(OH)]·2C6H12N2O, represents only the second example in the dimeric diorganotin(IV)-hydroxide-halide solvates [R2Sn(OH)Hal]2·2BB with Hal = I. As is usual for this class of compound, dimerization takes place via 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 (axial or equatorial) 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.
