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.

位置异构体对氯吡啶甲酸联吡啶三唑鎓杂化物光致变色行为的影响

具有两个类似联吡啶基三唑鎓和相似堆积模式的两个氯锑酸酯杂化物，{[2-bpt] ₂ [（SbCl ₅）Cl ₂ ]} _n（1）和{[4-bpt] ₂ [（SbCl ₅）Cl ₂ ]} _n（2）（2-bpt ²⁺ =质子化的3,5-双（吡啶-2-基）-1,2,4-三唑，4-bpt ²⁺设计并合成了质子化的3，5-双（吡啶-4-基）-1，2，4-三唑。不同的分子间电子相互作用和光致变色行为归因于位置异构体效应对受体电子缺乏和供体-受体匹配关系的显着调节。图1是第一个报道的光致变色氯锑酸杂化物。
