(2-Amido-3-oxidopyridinium-κN,O)dibenzyl-chloridotin(IV)

The Sn atom in the title compound, [Sn(C(7)H(7))(2)(C(5)H(5)N(2)O)Cl], shows a distorted C(2)ClNOSn trigonal-bipyramidal coordin-ation, with a Cl-Sn-O axial angle of 163.77 (3)°, but the C-Sn-C angle [141.43 (7)°] deviates from 120°. The chelating ligand exists in a zwitterionic form. Adjacent molecules are linked by an N-H(pyridinium)⋯O hydrogen bond, forming a chain running along the c axis of the orthorhombic unit cell.
