Complexes of the form M(PMH)2X2 can be isolated where M = CuII, CoII, NiII, ZnII, or CdII; PMH = 4,4′-di-ethoxycarbonyl-3,3′,5,5′-tetramethyldipyrromethene and X = Cl–, Br–, I–, CNS–, or NO3–. The presence of N–H bonds can be detected spectroscopically, indicating that co-ordination occurs through the basic pyrrole nitrogen. A number of the Cu, Ni, and Co complexes behave as 1:1 electrolytes in acetone
可以分离出M(PMH)2 X 2形式的配合物,其中M = Cu II,Co II,Ni II,Zn II或Cd II;PMH = 4,4'-二乙氧基羰基-3,3',5,5'-四甲基二吡咯亚甲基,X = Cl –,Br –,I –,CNS –或NO 3 –。可以通过光谱检测到NH键的存在,这表明配位是通过碱性吡咯氮发生的。许多铜,镍和钴配合物在丙酮中的电解质比例为1:1。磁性和光谱结果表明钴和可能的镍配合物为四面体结构。
