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.
在标题化合物[Sn(C₂₀H₁₉N₂O₃)Cl₃]中,Sn(IV)离子被一个三齿单阴离子席夫碱和三个经式氯离子围绕,呈六配位扭曲八面体几何构型。与氮原子相对的Sn-Cl键[2.366 (2) Å]比其他键[2.438 (2)和2.414 (2) Å]短。席夫碱配体中N-Sn-N角[76.19 (11)°]小于O-Sn-N角[87.89 (10)°]。未观察到经典的分子间氢键相互作用。晶体堆积呈现π-π堆积相互作用,在相关分子喹啉基团的酚盐环和苯环的质心之间距离为3.595 (2) Å。
