Synthesis and structural studies of Co(II) and Ni(II) complexes of glutaric- and adipic dihydrazides

摘要

Glutaric dihydrazide (GDH) and adipic dihydrazide (ADH) have been found to react with Co(II) chloride and Ni(II) chloride and nitrate in ethanolic solution to form complexes of the general empirical compositionsMLCl2,ML2Cl2and NiL2(H2O)2 (NO3)2whereM=Co(II), Ni(II) andL=GDH,ADH. Tetrahedral geometry has been proposed for 1∶1 complexes of Co(II) and octahedral geometry for the remaining complexes based on measurements of molar conductance, magnetic susceptibility, electronic and ir spectr
