成功合成并分离了一对异构的杂环配体L1和L2(LI:1.((吡啶-4-基)甲基)-1氢-苯并三唑,L2=2-(吡啶-4-基)甲基)-1氢-苯并三唑)).这类配体在构筑复杂的金属有机框架方面,具有许多优点.把这对配体分别和高氯酸银作用,得到了2个新的化合物1和2并测定了结构,分别为[Ag(L1)(C1O4)]n(1)和[Ag(L2)2]C104·H20(2).化合物1为一维双螺旋结构,而化合物2仅仅展现出零维结构.配体在结构上的细微差别可以导致所形成的配位化合物的结构的巨大差异.

A pair of isomeric heterocyclic ligands(LI=1-((pyridin-4-y1)methyl)-1-H-benzotriazole,L2=2-((pyridin-4-y1)methyl)-1-H-benzotriazole)was synthesized and separated.The obtained ligands are with lots of advantages in constructing complicated metal-organic frameworks(MOFs).The interaction of both ligands wag studied with crystals suitable for single-crystal X-ray analysis.Complex 1 gives a 1D double helical conformation,whereas complex 2 only exhibits a zero-dimensional structure.It is revealed that a small difference of ligands would lead the complete diversity of ultimate coordinated compounds'geometrical structure.CCDC:816547,1;816548,2.
