Co(II), Ni(II) and Cu(II) complexes are synthesized with thiosemicarbazone (L(1)) and semicarbazone (L(2)) derived from pyrole-2-carboxyaldehyde. These complexes are characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, mass, IR, electronic and EPR spectral studies . The molar conductance measurements of the complexes in DMSO correspond to non-electrolytic nature except Co(L1)2(NO3)2 and Ni(L1)2(NO3)2 complexes which are 1:2 electrolytes. All the complexes are of high-spin type. On the basis of spectral studies an octahedral geometry may be assigned for Co(II) and Ni(II) complexes except Co(L1)2(NO3)2 and Ni(L1)2(NO3)2 which are of tetrahedral geometry. A tetragonal geometry may be suggested for Cu(II) complexes.
用源自吡咯 - 2 - 甲醛的硫代半卡巴腙（L(1)）和半卡巴腙（L(2)）合成了钴（II）、镍（II）和铜（II）配合物。这些配合物通过元素分析、摩尔电导率、磁化率测量、质谱、红外光谱、电子光谱和电子顺磁共振光谱研究进行表征。除了钴（L1）₂（NO₃）₂和镍（L1）₂（NO₃）₂配合物为1:2电解质外，配合物在二甲基亚砜中的摩尔电导率测量结果表明其具有非电解质性质。所有配合物均为高自旋型。基于光谱研究，除了钴（L1）₂（NO₃）₂和镍（L1）₂（NO₃）₂为四面体几何构型外，钴（II）和镍（II）配合物可能具有八面体几何构型。铜（II）配合物可能具有四方几何构型。
