合成并表征了两个含有不同阴离子的双核镍(Ⅱ)配合物{[(tacn)Ni(H_2O)]_2(μ-C_2O_4)}I_2·2H_2O(1)和{[(tacn)Ni(H_2O)]_2(μ-C_2O_4)}(ClO_4)_2·2H_2O(2)(tacn=1,4,7-三氮杂环壬烷).晶体结构分析表明这两个配合物中,两个Ni离子通过草酸根桥联,每个Ni离子还与一个大环配体tacn上的三个氮原子和一个水分子配位形成变形八面体结构.结晶水和配位水之间通过氢键相连.在紫外-可见区测定了配合物的固体反射谱和溶液吸收谱.
Two binary nickel (Ⅱ) complexes with different anions were synthesized and characterized. [(Tacn) Ni (H_2O)] _2 (μ_C_2O_4)} I_2 · 2H_2O and {[(tacn) ] _2 (μ-C_2O_4)} (ClO_4) _2 · 2H_2O (2) (tacn = 1,4,7-triazacyclononane). The crystal structure analysis showed that two Ni ions Oxalate bridge, each Ni ion also with a large ring ligand tacn three nitrogen atoms and a water molecule coordination to form a deformed octahedral structure. Crystalline water and coordination water connected by hydrogen bonds between the UV - Visible zone The solid reflectance and solution absorption spectra of the complexes were determined.
