Studies of bi-valent complexes of Co(II), Ni(II), Mn(II) and Zn(II) with Hydrazine carboxylic acid and Formyl hydrazine carboxylic acid

Abstract

Complexes of hydrazine carboxylic acid (Hhyc) and formyl hydrazine carboxylic acid (HCH=N-NH-COOH) abbreviated as (Hhyc) of Co(ll), Mn(II), Ni(II) and Zn(II) of composition M(hyc)2 (NH2-NH2).H2SO4.2H2O, M (fhyc) (H2O)2 SO4 and Zn(Hhyc) (NH2 NH2) SO4 2H2O have been prepared and characterized by u-v, i.r., magnetic susceptibility and derivatographic studies of complexes. From above studies polymeric structure is assigned to both M(NH2-NHCOO)2N2H4 H2SO4.2H2O and M(CH2=N-NHCOOH)2 (H2O)2 SO4 type of complexes.
