Octakis(2-chlorobenzyl)di-μ2-hydroxido-di-μ3-oxido-bis(2-phenylacetato)tetratin(IV)

Abstract

The asymmetric unit of the title compound, [Sn4(C7H6Cl)8(C8H7O2)2O2(OH)2], comprises one-half of the centrosymmetric tin(IV) complex. μ3-Oxide and μ2-hydroxide bridges link the four five-coordinate SnIV atoms to generate three fused four-membered Sn—O—Sn—O rings in a ladder-like structure. The two endocyclic Sn atoms each bind to two μ3-oxide anions and a μ2-hydroxide ligand, together with two 2-chlorobenzyl groups. The exocyclic Sn atoms each carry a monodentate phenylacetate ligand, two 2-chlorobenzyl groups, and μ3-oxide and μ2-hydroxide ligands. Both types of Sn atoms adopt a distorted trigonal–bipyramidal coordination geometry. The molecular conformation is stabilized by intramolecular O—H...O interactions involving the μ2-hydroxide ligands and the C=O group of the phenylacetate ligand.
