N-Butyl-dichlorido(2-{(1E)-1-[2-(pyridin-2-yl)hydrazin-1-yl-idene]eth-yl}phenolato)tin(IV).

ABSTRACT: Two independent mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(4)H(9))(C(13)H(12)N(3)O)Cl(2)]. The Sn atom in each is coordinated by the tridentate ligand via the phenoxide O, hydrazine N and pyridyl N atoms, forming five- and six-membered chelate rings. The approximately octa-hedral coordination geometry is completed by the α-C atom of the n-butyl group (which is trans to the hydrazine N atom) and two mutually trans Cl atoms. Differences between the mol-ecules are evident in the relative planarity of the chelate rings and in the conformations of the n-butyl groups [C-C-C-C = 177.2 (5) and -64.4 (11)°]. Significant differences in the Sn-Cl bond lengths are related to the formation of N-H⋯Cl hydrogen bonds, which link the mol-ecules comprising the asymmetric unit into
