In the title compound, [Sn(CH3)2(C14H9ClN2O3)], the SnIV ion is coordinated by one N and two O atoms from the tridentate 5-chloro-2-hydroxy-N′-(2-oxidobenzylidene)benzohydrazidate (L) ligand and two methyl groups in a distorted trigonal–bipyramidal geometry. In the ligand, the hydroxy group is involved in an intramolecular O—H⋯N hydrogen bond and the two aromatic rings form a dihedral angle of 5.5 (1)°. In the crystal, weak intermolecular C—H⋯O hydrogen bonds and π–π interactions between the aromatic rings [centroid–centroid distance = 3.816 (3) Å] link the molecules into centrosymmetric dimers.

The reaction was carried out under nitrogen atmosphere. The Schiff base ligand (0.2 mmol) was added to 30 ml e thanol with sodium ethoxide (0.4 mmol). The mixture was stirred for 0.5 h and then dichlorodimethyltin (0.2 mmol) was added.And the mixture was stirred for 12 h under reflux. After cooling to room temperature, the mixture was filtered and evaporated to dryness. The resulting solid, was then recrystallized from dichloromethane-petroleum ether (1:1, v/v). Anal. Calcd (%) for C16H15ClN2O3Sn (Mr = 437.44): C, 43.93; H, 3.46; N, 6.40; O, 10.97. Found (%): C, 43.90; H, 3.42; N, 6.35; O, 10.9.
The H atoms were positioned geometrically (C–H 0.93-0.96 Å; O–H 0.82 Å), and refined as riding, with Uiso(H) = 1.2-1.5 Ueq of the parent atom.

Organotin(IV) compounds of hydrazone Schiff bases were reported by Hong et al. (2010). In continuation of our study of hydrazone Schiff base organotin(IV) compounds (Li et al., 2009), we have synthesized the title compound, (I).
In (I) (Fig. 1), the tin center is five-coordinated in a distorted trigonal bipyramidal geometry, being surrounded by two C atoms from the alkyl and one N atom, two O atoms from the Schiff base ligand. So the ligand coordinated to the tin atom as a tridentate ligand. In the tridentate ligand, two aromatic rings form a dihedral angle of 5.5 (1)°. The O atoms coordinate the Sn center with different bond lengths - for carbonyl O2 atom Sn—O2 = 2.183 (2) Å, and for hydroxy O3 atom Sn—O3 = 2.078 (3) Å. Similar structural parameters were observed in the related compound (Yearwood et al., 2002). In (I), the angles o C15–Sn–C16, C15–Sn–O3 and C16–Sn–O3 are 129.30 (15)°, 100.22 (14)° and 95.08 (14)°, respectively, indicating the distorted trigonal bipyramidal coordination geometry.
In the crystal structure, weak intermolecular C—H···O hydrogen bonds (Table 1) and π—π interactions between the aromatic rings [centroid-to-centroid distance of 3.816 (3) Å] link the molecules into centrosymmetric dimers (Fig.2 ).
