Ni(Ⅱ)配合物在非水溶液中的合成和性质研究

Study on Properties and Synthesis of Nickel(Ⅱ)-Complex in Non-aqueous Solution

以无水乙醇为反应介质 ,找出合成四面体配合物 (Bu4N) 2 NiBr4的适宜实验条件 ,制备出四面体(Bu4N) 2 NiBr4和八面体Ni(NH3) 6 Br2 二种固体配合物 ,并研究了配合物的电子光谱、红外光谱、摩尔电导等 .磁化率测定结果证实 ,四配位的 (Bu4N) 2

In absolute alcohol,the experiment condition of synthesis of tetrahedral complex (Bu 4N) 4NiBr 4 was concluded.Two-type solid complexes were prepared:tetrahedral complex (Bu 4N) 2NiBr 4 and octahedral complex Ni(NH 3) 6Br 2.The properties of complexes(electronic spectrum,in spectrum,molar conductivity etc.)were studied.The result of magnetic susceptibility showed tetra-coordination complex(Bu 4N) 2NiBr 4 was tetrahedral configuration.
