16-tetraene (L), reacts with copper(II) chloride or copper(II) tetrafluoroborate hexahydrate to give complexes [Cu3Cl6L2] (1) or [CuL2(H2O)2](BF4)2(H2O) (2), respectively. According to single crystal X-ray analysis, both complexes were found to be coordination polymers. In the crystal structure of complex 1, there are neutral linear bibridged trinuclear units Cu3Cl6, in which the copper atoms are linked together
大环双核四唑,2,2,5,5-四甲基-12-oxa-1,6,7,8,16,17,18,19-八氮杂三环[13.2.1.16,9] nonadeca-7,9(19 ),15(18),16-四烯(L)与氯化铜(II)或四氟硼酸铜(II)六水合物反应生成配合物[Cu 3 Cl 6 L 2 ](1)或[CuL 2(H 2 O) )2 ](BF 4)2(H 2 O)(2)。根据单晶X射线分析,发现两种络合物均为配位聚合物。在配合物1的晶体结构中,存在中性线性双桥三核单元Cu3 Cl 6,其中铜原子通过双氯桥连接在一起。由于Cu 3 Cl 6单元的末端铜原子与配体L的四唑环氮原子之间的配位键Cu-N,相邻的Cu 3 Cl 6单元通过两个桥连的大环配体L相互键合,形成聚合物链。在复杂2然后,铜原子通过四唑环氮原子与三个配体L键合,并与两个水分子键合,形成金属的方形-金字塔形配位。在这种络合物中,两个独立
