title: {4-Hy-droxy-N'-[(2E,3Z)-4-oxido-4-phenyl-but-3-en-2-yl-idene]benzo-hydra-zidato}diphenyl-tin(IV) methanol monosolvate.
abstract: Two independent diphenyl-tin mol-ecules and two independent methanol mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(6)H(5))(2)(C(17)H(14)N(2)O(3))]·CH(3)OH. The Sn atom in each is five-coordinated by a tridentate ligand and the ipso-C atoms of the Sn-bound benzene substituents. The resulting C(2)N(2)O donor set defines a coordination geometry that is inter-mediate between trigonal-bipyramidal (TP) and square-pyramidal (SP), with one mol-ecule slightly tending towards TP and the other slightly towards SP. The mol-ecules differ in terms of the relative orientations of the terminal benzene rings [dihedral angles = 45.71 (18) and 53.98 (17)°] and of the Sn-bound benzene substituents [dihedral angles = 59.5 (2) and 45.77 (18)°, respectively]. The most prominent feature of the crystal packing is the formation of four-mol-ecule aggregates via O-H⋯O and O-H⋯N hydrogen bonds, in which the hy-droxy group is connected to a methanol mol-ecule which, in turn, is linked to a non-coordinating N atom. Weak C-H⋯π inter-actions also occur.
