Abstract

The complexes of SnCl₄ with diglyme and 15-crown-5 polyethers, namely [SnCl₄(diglyme)] (I), [SnCl₄(H₂O)₂]₃·2(15-crown-5) (II) and [SnCl₄(15-crown-5)]₂·Et₂O (III), were obtained and characterized by single crystal X-ray diffraction (scXRD) analysis. The compounds I and III were additionally characterized by powder X-ray diffraction, thermal and elemental analyses. The crystal structures of I and III are composed of discrete [SnCl₄(diglyme)] and [SnCl₄(15-crown-5)] molecules, respectively. In these structures, the polyethers act as bidentate ligands, completing the octahedral environment of tin(IV). The crystal structure of II comprises the cis- and trans-SnCl₄(H₂O)₂ isomers, which form a hydrogen bonded network with 15-crown-5 molecules and chloride ligands through coordinated water molecules.

SnCl4与聚醚配体的络合：[SnCl4（二lyme）]、[SnCl4(H2O)2]3·2（15-crown-5）和[SnCl4(15-crown-5)]2·Et2O的晶体结构

得到了SnCl4与二lyme和15-crown-5聚醚的配合物[SnCl4（二lyme）] (I)、[SnCl4(H2O)2]3·2(15-crown-5) （II）和[SnCl4(15-crown-5)]2·Et2O (III)，并用单晶x射线衍射（scXRD）分析对其进行了表征。化合物I和III通过粉末x射线衍射、热分析和元素分析进行了表征。I和III的晶体结构分别由离散的[SnCl4（二lyme）]和[SnCl4(15-crown-5)]分子组成。在这些结构中，聚醚作为双齿配体，完成了锡（IV）的八面体环境。II的晶体结构包括顺式sncl4 (H2O)2和反式sncl4 (H2O)2异构体，它们通过配位的水分子与15冠5分子和氯配体形成氢键网络。
