Magnetic and Spectral Properties of Fe(II), Fe(III), Co(II), Ni(II), CuI(II) and Pd(II) Chelates of 2'-Hydroxy-4- Methoxy-5'-Methylchalkone Oxime (HMMCO)

Chemistry Department, Nagpur University Campus, Nagpur-440 010 Manuscript received 23 May 1978, revised 9 November 1978, accepted 22 December 1978 Studies on the complexes of transition metals with bidentate oxime ligand 2'-hydroxy-4-methoxy-5'-methylchalkone oxime (HMMCO) has been carried out. On the basis of elemental analysis, molar conductance and thermal analysis the complexes have been assigned the formulae Fe(II)(HMMCO)25H2O, Fe(Ill)(HMNICO)36H2O, Co(HMMC0)23H2O, Ni(HMMC0)22H2O,Cu(HMMC0)23H2O and Pd(HMMCO)2. The attempts have been made to assign their probable structures with the aid of magnetic data, electronic and i.r. spectral data
