Two chloroantimonate hybrids with isomeric bipyridyltriazoliums and similar packing patterns, {[2-bpt]2[(SbCl5)Cl2]}n (1) and {[4-bpt]2[(SbCl5)Cl2]}n (2) (2-bpt2+ = protonated 3,5-bis(pyridine-2-yl)-1,2,4-triazole, 4-bpt2+ = protonated 3,5-bis(pyridine-4-yl)-1,2,4-triazole), have been designed and synthesized. Distinct intermolecular electronic interactions and photochromic behaviors are attributed to the remarkable modulation of positional isomeric effect on the electron deficiency of the acceptors and donor-acceptor matching relationship. 1 is the first reported photochromic chloroantimonate hybrid.
设计并合成了两种具有异构联吡啶三唑鎓且堆积模式相似的氯锑酸盐杂化物，{[2-bpt]2[(SbCl5)Cl2]}n（1）和{[4-bpt]2[(SbCl5)Cl2]}n（2）（2-bpt2+ = 质子化的3,5-双（吡啶-2-基）-1,2,4-三唑，4-bpt2+ = 质子化的3,5-双（吡啶-4-基）-1,2,4-三唑）。独特的分子间电子相互作用和光致变色行为归因于位置异构效应受体缺电子性和供体-受体匹配关系的显著调节。1是首次报道的光致变色氯锑酸盐杂化物。
