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

Abstract:
The title compound, di-μ-hydroxido-bis-[iodido-diphenyl-tin(IV)]-1,3-di-methyl-imidazolidin-2-one (1/2), [Sn(C6H5)2I(OH)]·2C6H12N2O, represents only the second example in the dimeric diorganotin(IV)-hydroxide-halide solvates [R 2Sn(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.

The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
