[N'-(3-Meth-oxy-2-oxidobenzyl-idene)nicotinohydrazidato]diphenyl-tin(IV).

ABSTRACT: The asymmetric unit of the title compound, [Sn(C(6)H(5))(2)(C(14)H(11)N(3)O(3))], contains two crystallographically independent mol-ecules that differ predominantly in the torsion of the phenyl rings. In both mol-ecules, the Sn(IV) ion is in a distored trigonal-bipyramidal geometry. The Sn-O distances are in the range 2.055 (2)-2.143 (2) Å.
