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.
