Abstract


Some hydroxamic acids eg. [L1=3,4,5-trimethoxy benzohydroxamic acids (TMBHA), L2= Nphenyl–3,4,5-trimethoxy benzohydroxamic acid (NPTMBHA), L3=3,4-dimethoxy benzohydroxamic acid (DMBHA) and L4=N-phenyl-3,4-dimethoxy benzohydroxamic acid (NPDMBHA) prepared and reacted with L’=Potassium hexathiocynato chromium (III) tetra hydrate K3[Cr(SCN)6]4H2O. The mixed ligand complexes of hydroxamic acids characterized with the help of repeated melting point identification, by I.R.studies, magnetic moment, molar conductance and by elemental analysis(C, H and N).The geometry of complexes were found to be octahedral .On the basis of these facts the structure of the metal complexes found to be K2 [M(L’)4(L1)], K[M(L’)2(L2)2], K[M(L’)2(L3)2] and K[M(L’)2(L4)2].
