In the title complex, [Sn(CH3)2(C18H11ClN2O2)], the SnIV ion is coordinated by two O atoms and an N atom from a 4-chloro-N′-[(2-oxidonaphthalen-1-yl)methylidene]benzohydrazidate ligand and two C atoms from two methyl ligands in a distorted trigonal–bipyramidal geometry [Sn—O = 2.092 (3) and 2.144 (3) Å; Sn—N = 2.160 (4) Å]. The dihedral angle between the naphthalene ring system and the benzene ring is 8.6 (2)°. In the crystal, adjacent molecules are linked by weak C—H⋯O hydrogen bonds, forming a chain along the b-axis direction.

2-hydroxy-1-naphthaldehyde 4-chlorobenzoylhydrazone (1 mmol) and sodium ethoxide (1 mmol) were added to the solution of dry methanol(30 ml) and stirred for 10 mins. Dimeyltin dichloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 4 h. The resulting clear solution was evaporated under vacuum. The product was crystallized from a mixture of dichloromethane/ethanol(1:1) to yield orange blocks of the title compound (yield 73%).
The H atoms were positioned geometrically, with methyl C—H distances of 0.96 Å and aromatic and aldehydic C—H distances of 0.93 Å, and refined as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C) for the methyl groups.

The chemistry of organotin(IV) derivatives is a subject of study with growing interest due to their significant antimicrobial properties as well as antitumor activities (Hong et al., 2013). As a part of our ongoing investigations in this field we have synthesized the title compound and present its crystal structure here. The molecular structure of the title compound, (I), is shown in Fig. 1. The Sn atom has distorted trigonal-bipyramidal geometry, with atoms O1 and O2 in axial positions [O1—Sn1—O2 = 153.39 (13) °] and the atoms C19, C20 and N2 in equatorial positions. The sum of the equatorial angles is 359.9 °, indicating approximate coplanarity for these atoms. The Sn1—N2 bond length is 2.160 (4) Å close to the sum of the non-polar covalent radii 2.15 Å, indicating a strong Sn—N interaction. The O atoms coordinate to the Sn atom with one shorter [2.092 (3) Å] and one longer [2.144 (3) Å] bond. The dihedral angle between the naphthalene ring system (C9-C18) and the benzene ring (C1-C6) is 8.6 (2)°.
