{4-Amino-N'-[(2-oxidonaphthalen-1-yl)methyl-idene]benzohydrazidato}di-methyl-tin(IV).

In the title compound, [Sn(CH3)2(C18H13N3O2)], the Sn(IV) ion is coordinated by one N and two O atoms from the tridentate 4-amino-N'-[(2-oxidonaphthalen-1-yl)methyl-idene]benzohydrazidate(2-) ligand and two C atoms from methyl ligands in a distorted trigonal-bipyramidal geometry. The dihedral angle between the naphthalene ring system and the benzene ring is 19.2 (2)°. In the crystal, weak N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along [010].
