[N'-(5-Bromo-2-oxidobenzyl-idene-κO)-3-hydr-oxy-2-naphthohydrazidato-κN',O]dimethyl-tin(IV)

The Sn(IV) atom in the title compound, [Sn(CH(3))(2)(C(18)H(11)BrN(2)O(3))], shows a distorted cis-C(2)NO(2)Sn trigonal-bipyramidal coordination geometry, with an axial O-Sn-O angle of 155.27 (9)°. The presence of an intra-molecular O-H⋯N hydrogen bond between the amido N atom and hydr-oxy H atom in the Schiff base ligand helps to stabilize the overall mol-ecular structure.
