Bis(μ-2-{[oxido(phenyl)methylidene]hydrazinylidene}propanoato)bis[dibenzyl(ethanol)tin(IV)]

Abstract

In the title complex, [Sn2(C7H7)4(C10H8N2O3)2(C2H5OH)2], the Sn(IV) atom is seven-coordinated in a distorted pentagonal–bipyramidal geometry by three O atoms and one N atom from the pyruvate benzoyl hydrazone ligand, one ethanol O atom and two axial C atoms from trans-benzyl groups, thus forming a dimeric molecule (overline{1} symmetry) via weak Sn—O interactions. The C atoms of one phenyl ring and the ethanol molecule are disordered over two sets of sites with site-occupancy factors of 0.57 (5):0.43 (5) and 0.79 (2):0.21 (2), respectively. Intermolecular O—H...O hydrogen bonds stabilize the crystal structure.
