copper(II) dichlorido complexes [Cu(Ln′)Cl2] (1 (n = 1) and 2 (n = 0)) of the neutral N3 type ligands, tris(3,5-diisopropyl-1-pyrazolyl)methane (L1′) and tris(3,5-dimethyl-1-pyrazolyl)methane (L0′) were synthesized and the influence of ligand framework and charge on their structure and physicochemical properties was investigated. From reaction with one equivalent of sodium perchlorate, binuclear copper(II)

氯化物络合物[Cu(Ln')(µ-Cl)] 2(
ClO4)2(3(n = 1)和4(n = 0))获得了。所有结构均通过X射线晶体学测定。这些配合物还通过光谱技术进行了表征,即UV-Vis / DR,IR / far-IR和ESR光谱。对于双核络合物,可变温度磁化率测量会产生-3.0(1)和+4的J耦合常数。33(8)cm-1分别适用于3和4; Cu-Cl-Cu角分别为96.89(3)和96.11(5)度。
