2-hydroxido-di-3-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. 3-Oxide and 2-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 3-oxide anions and a 2-hydroxide ligand, together with two 2-chlorobenzyl groups. The exocyclic Sn atoms each carry a monodentate phenylacetate ligand, two 2-chlorobenzyl groups, and 3-oxide and 2-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 2-hydroxide ligands and the C=O group of the phenylacetate ligand.
