Trichlorido{2-dimeth-oxy-methyl-4-methyl-6-[(quinolin-8-yl)imino-meth-yl]phenolato-κN,N',O}tin(IV).

In the title compound, [Sn(C(20)H(19)N(2)O(3))Cl(3)], the Sn(IV) ion is surrounded by a tridentate monoanionic Schiff base and by three meridional chloride ions in a six-coordinated distorted octa-hedral geometry. The Sn-Cl bond [2.366 (2) Å] trans to nitro-gen 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 inter-molecular hydrogen-bonding inter-actions are observed. The crystal packing exhibits π-π stacking inter-actions, 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 mol-ecules.
