合成了一种新的有机-无机杂化化合物[{p-（CH 3）2NH-C6 H4-NH3}2Cl][BiI 6]，并确定了其晶体结构。杂化物由无机阴离子[BiI 6]3−和有机阳离子[{p-（CH 3）2NH-C6 H4-NH3}2Cl]3+组成。[BiI 6]3−阴离子通过阴离子共价I. I相互作用，形成沿着四面体晶胞轴向的链。在阳离子部分，Cl−阴离子与p-（CH 3）2NH-C6 H4-NH32+阳离子的氢原子形成四个（N）H. Cl氢键，形成二维亚结构。交替共价键和I... I卤素键的阴离子子结构和阳离子-阴离子氢键提供了一个三维的超分子结构的形成与1.93 eV的带隙。
A new organic-inorganic hybrid [{p-(CH3)2NH—C6H4—NH3}2Cl][BiI6] was synthesized and its crystal structure was established. The hybrid consists of an inorganic anion [BiI6]3−and an organic cation [{p-(CH3)2NH-C6H4-NH3}2Cl]3+. The [BiI6]3−anions are linkedvianon-covalent I...I interactions between axial atoms of neighboring anions to form chains running along thecaxis of the tetragonal unit cell. In the cationic part, the Cl−anion is involved in four (N)H…Cl hydrogen bonds with hydrogen atoms of thep-(CH3)2NH—C6H4—NH32+cation, forming a two-dimensional substructure. Alternating covalent and I...I halogen bonds in the anionic substructure and cation—anion hydrogen bonds provide the formation of a three-dimensional supramolecular structure with a band gap of 1.93 eV.
