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
Co(II),Ni(II)和Cu(II)配合物与由吡咯-2-羧醛衍生的硫半脲(L(1))和半脲(L(2))合成。这些配合物的特征在于元素分析,摩尔电导,磁化率测量,质量,IR,电子和EPR光谱研究。DMSO中配合物的摩尔电导测量值与非电解性质相对应,除了Co(L1)2(NO3)2和Ni(L1)2(NO3)2配合物是1:2电解质外。所有复合体均为高旋转型。根据光谱研究,可以为Co(II)和Ni(II)配合物分配八面体几何形状,但Co(L1)2(NO3)2和Ni(L1)2(NO3)2具有四面体几何形状。对于Cu(II)配合物,可能建议采用四边形的几何形状。
