摘要:

合成了一个柔性配体1,3-二(N-咪唑基甲基)苯(mbix)(1), 并将其与不同Cu盐组装, 得到3个新配合物[Cu(mbix)2(H2O)]·2NO3·CH3OH(2), [Cu(mbix)(N3)(OAc)]·CH3OH(3)和[Cu(mbix)2]·SiF6·2CH3OH(4), 并对其进行了元素分析、红外光谱及X 射线单晶结构分析表征. 配合物2拥有二维二重贯穿结构, 配合物3中两个铜离子通过两个叠氮酸根桥连成双核铜, 它再通过配体连接形成一维绞链状结构, 而配合物4通过配体桥联成一维无限链状结构. 结果显示, 平衡阴离子在配合物的组装过程中起着非常重要的作用. 此外还对配体及3个配合物中配体的构象进行了理论计算.

Abstract:

Three novel coordination complexes, [Cu(mbix)2(H2O)]·2NO3·CH3OH(2), [Cu(mbix)(N3)(OAc)]·CH3OH(3) and [Cu(mbix)2]·(SiF6)·2(CH3OH)(4), with a novel flexible ligand 1,3-bis(imidazol-1-ylmethyl)benzene(mbix, 1) with Cu salts, were prepared and characterized by elemental analysis, IR and X-ray single-crystal diffraction. Complex 2 exhibit a two-dimensional two-fold interpenetrating network; complex 3 process a hinge-chain structure with dinuclear Cu(Ⅱ) clusters as secondary building units which are bridged through azide anion, while complex 4 features a one-dimensional infinite chain structure. The results show that the counteranions play important roles in the assembly of the complexes. Moreover, theoretical calculations were carried about the conformation of the ligand in three complexes.
