{4-Hy-droxy-N'-[(2E,3Z)-4-oxido-4-phenyl-but-3-en-2-yl-idene]benzo-hydrazidato}dimethyl-tin(IV)

The Sn(IV) atom in the title compound, [Sn(CH(3))(2)(C(17)H(14)N(2)O(3))], is five-coordinated within a C(2)N(2)O donor set provided by the N,N,O-tridentate ligand and two methyl groups. The resultant coordination geometry is inter-mediate between trigonal-bipyramidal and square-pyramidal. In the crystal, supra-molecular zigzag chains propagating along the c- axis direction are mediated by O-H⋯O hydrogen bonds, and weak C-H⋯π inter-actions consolidate the packing.
