For the preparation of the title compound, a solution of 2,4-dimethyl-N-(pyridin-2-ylmethylene)aniline (0.210 g, 1 mmol) in ethanol (10 ml) was added to a solution of Sn(CH3)2Cl2 (0.220 g, 1 mmol) in methanol (10 ml). The resulting colorless solution was stirred for 2 hra at room temperature and then left to evaporate slowly at 3–5°C. After two weeks, yellow crystals of the title compound were isolated (yield: 0.329 g, 76.4%; m.p.: 416–419 K).
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (CH) and 0.96 (CH3) Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C).

Compounds with an azomethine group, C═N, are known as Schiff bases, which are usually synthesized from the condensation of primary amines and active carbonyl groups. The Schiff bases and their metal complexes are an important class of compounds in medicinal and pharmaceutical field. They show biological applications including antibacterial (Azza & Abu, 2006; Dudek & Dudek, 1966), antifungal (Pandeya et al., 1999; Panneerselvam et al., 2005; Singh et al., 2006; Sridhar et al. 2001) and antitumor activities (Mladenova et al., 2002; Walsh et al., 1996) and industrial uses, especially in catalysis (McAuliffe et al., 1986), dying (Papić et al., 1994), electronic and optic (Vlcek, 2002). In our ongoing studies on the synthesis and structural determination of transition metal complexes with iminopyridine ligands (Fallah Nejad et al., 2010; Talei Bavil Olyai et al., 2008, 2010a,b), we report here the crystal structure of the title compound, derived from the Schiff base ligand, 2,4-dimethyl-N-(pyridin-2-ylmethylene)aniline.
The title compound consists of two crystallographically independent molecules in the asymmetric unit, both with a similar six-coordinated environment. The SnIV atom is surrounded by two (one imino and one pyridine) N atoms belonging to the bidentate chelating iminopyridine ligand, two methyl groups and two Cl atoms (Fig. 1). The Sn—N, Sn—C and Sn—Cl bond distances (Table 1) are within normal ranges, which are similar to those reported in literature (Ali et al., 2004; Labisbal et al., 2006). The bond lengths and angles around the SnIV atoms show deviation from an ideal octahedral geometry. The Sn1—N2 and Sn2—N4 imine distances [2.468 (8) and 2.449 (8) Å] are approximately close to the Sn1—N1 and Sn2—N3 pyridine distances [2.470 (5) and 2.456 (5) Å]. The N2—C9 and N4—C25 bond lengths of 1.254 (10) and 1.277 (10) Å are typical for the C═N double bond.
In the crystal, intermolecular C—H···Cl hydrogen bonds (Table 2, Fig. 2) link the molecules, which may be effective in the stabilization of the structure. π–π contacts between the pyridine rings, Cg2i···Cg5 [Cg2 and Cg5 are the centroids of N1, C10—C14 and N3, C26—C30 rings, respectively; symmetry code: (i) 1/2+x, 3/2-y, z], further stabilize the structure, with centroid–centroid distance of 3.761 (4) Å (Fig. 3).
