Octa-kis(2-chloro-benz-yl)di-μ(2)-hydroxido-di-μ(3)-oxido-bis-(2-phenyl-acetato)tetra-tin(IV).

ABSTRACT: The asymmetric unit of the title compound, [Sn(4)(C(7)H(6)Cl)(8)(C(8)H(7)O(2))(2)O(2)(OH)(2)], comprises one-half of the centrosymmetric tin(IV) complex. μ(3)-Oxide and μ(2)-hydroxide bridges link the four five-coordinate Sn(IV) 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 μ(3)-oxide anions and a μ(2)-hydroxide ligand, together with two 2-chloro-benzyl groups. The exocyclic Sn atoms each carry a monodentate phenyl-acetate ligand, two 2-chloro-benzyl groups, and μ(3)-oxide and μ(2)-hydroxide ligands. Both types of Sn atoms adopt a distorted trigonal-bipyramidal coordination geometry. The mol-ecular conformation is stabilized by intra-molecular O-H⋯O inter-actions involving the μ(2)-hydroxide ligands and
