Trichlorido{2-dimethoxymethyl-4-methyl-6-[(quinolin-8-yl)iminomethyl]phenolato-κ3N,N′,O1}tin(IV)

In the title compound, [Sn(C20H19N2O3)Cl3], the SnIV ion is surrounded by a tridentate monoanionic Schiff base and by three meridional chloride ions in a six-coordinated distorted octahedral geometry. The Sn—Cl bond [2.366 (2) Å] trans to nitrogen is shorter than the others [2.438 (2) and 2.414 (2) Å]. The N—Sn—N angle [76.19 (11)°] is smaller than the O—Sn—N angle [87.89 (10)°] in the Schiff base ligand. No classical intermolecular hydrogen-bonding interactions are observed. The crystal packing exhibits π–π stacking interactions, with a distance of 3.595 (2) Å between the centroids of the phenolate ring and the benzene ring of the quinoline group of inversion-related molecules
