摘要
合成了二个新的一个分子中含有二个羧基桥联的双核 Cu(Ⅱ)配合物[Cu(Phen)(HCOO)]_2·(NO_3)_2·3H_2O(1),[Cu(Phen)(CH_3COO)]_2·(NO_3)_2·3H_2O(2)和一个一分子中含有一个羧基桥和一个羟基桥的双核 Cu(Ⅱ)配合物[Cu_2(OH)(C_2H_5COO)(Phen)_2]·(NO_3)_2·H_2O(3)以及单核 Cu(Ⅱ)配合物[Cu(Phen)(CF_3COO)]·(NO_3)·H_2O(4)(其中 Phen 为2,9-=甲基-1,10-啡罗啉).通过元素分析,等离子光谱、红外光谱,TG 及 X-射线粉末衍射分析对四个配合物进行了初步表征,测定了它们的氧化还原电位及电导.通过分析讨论,确定了配合物中羧基的配位方式.
Two new dicopper(Ⅱ)complexes with two carboxyl bridgings in one molecule [Cu(Phen)(HCOO)]_2·(NO_3)_2·3H_2O(1),[Cu(Phen)(CH_3COO)]_2·(NO_3)_2·3H_2O(2),one dicopper(Ⅱ)complex with a carboxyl bridging and a hydroxo bridging in one molecule [Cu_2(OH)(C_2H_5COO)(Phen)_2]·(NO_3)_2·H_2O(3),and one mononuclear Cu(Ⅱ)complex [Cu(Phen)(CF_3COO)]·(NO_3)·H_2O(4)(Phen=2,9-dimethyl-1,10-phenanthrolin)were synthesized and characterized by means of elemental analyses,ICP,IR,TG and X-ray diffraction.Their electronic conductivity and CV waves were measured.The coordination modes of carboxyl moieties in all the title complexes were determined.
