The octahedral complexes of the type K[Cr(NTA)(A-A)] and K2[Cr(NTA)(B)2] where NTA = nitrilotriacetate, A-A = deprotonated histidine, proline phenylanthranilic acid, imminodiacetic acid, glutamic acid, aspartic acid, anthranilic acid, threonine, methionine, valine, glycylglycine and glycine and B = deprotonated nicotinic acid, hippuric acid, m and p-aminobenzoic acid, have been prepared and characterised
类型为K [Cr(NTA)(AA)]和K 2 [Cr(NTA)(B)2 ]的八面体络合物,其中NTA =次氮基三乙酸盐,AA =去质子化的组氨酸,脯氨酸苯基邻氨基苯甲酸,亚氨基二乙酸,谷氨酸,天冬氨酸酸,邻氨基苯甲酸,苏氨酸,蛋氨酸,缬氨酸,甘氨酰甘氨酸和甘氨酸,以及B =去质子化的烟酸,马尿酸,m和对氨基苯甲酸,已基于化学分析,红外光谱,反射率和电子光谱研究进行了制备和表征,磁,电导和极谱测量。配位场的参数,10 DQ,B和β 35被报告,并与来自其它类型的研究中获得的观察结果相关。
