The influence of the supporting electrolyte and the solvent of crystallisation on the nature of cadmium complexes of 2,6-bis(1-salicyloylhydrazonoethyl)pyridine (H4daps), obtained by an electrochemical procedure, has been investigated. [Cd(H2daps)(H2O)2] (1), [Cd(H2daps)(H2O)(CH3)2CHOH}] (2), [Cd(H3daps)Cl]·CH3CN·0.25H2O (3), [Cd(H3daps)Cl(CH3OH)]·2H2O·CH3OH (4), and [Cd(H2daps)Cl(H2O)]N(CH3)4 (5)
已经研究了支持电解质和结晶溶剂对通过电化学方法获得的 2,6-双 (1-水杨酰肼基乙基) 吡啶 (H4daps) 镉配合物的性质的影响。[Cd(H2daps)(H2O)2] (1), [Cd(H2daps)(H2O)(CH3)2CHOH}] (2), [Cd(H3daps)Cl]·CH3CN·0.25H2O (3), [ Cd(H3daps)Cl(CH3OH)]·2H2O·CH3OH (4) 和 [Cd(H2daps)Cl(H2O)]N(CH3)4 (5) 都已被分离出来并进行了晶体学表征。X 射线衍射研究表明,3 中的镉原子处于不寻常的五角锥 [CdN3O2Cl] 几何结构中,而在其他化合物中,镉原子处于双锥五角形环境中。有机配体在 1、2 和 5 中作为五齿双阴离子配体,在 3 和 4 中作为五齿单阴离子配体。
