Abstract: The synthesis of six new mononuclear and binuclear dioxomolybdenum(VI) chelates of compositions,[MoO2(OH)(L)]2, where L = N-(4' -butyrylidene-3'-methyl-1'phenyl-2'-pyrazolin-5' -one)-p-anisidine (B UMPHP-PAH, I), N( 4' -butyrylidene-3'-methyl- 1' -phenyl-2'-pyrazolin-5'-one)-m-phenetidine (BUMPHP-MPH, II) or N-(4'-butyrylidene-3'-methyl-1 'phenyl-2'-pyrazolin-5'-one)-p-toluidine (BUMPHP-PTH, III),[MoO2(L)], where L = N,N' -bis-(4' -butyrylidene-3' -methyl-1' -phenyl-2'-pyrazolin-5'-one)-o-phenylenediamine (BUMPHPOPHDH2, IV), [MoO2 (H2O)(L)], where L:=N,N'-bi s(4'-butyryl idene-3' -methyl-1' -phenyl-2' -pyrazolin-5' -one)-m-phenylenediamine (BUMPHP-MPHDH2,V) and [{ MoO2(OH)}2 (L)],where L=N,N' -bis(4' -butyrylidene-3' -methyl-1 '-phenyl-2' –pyrazolin-5'-one)-benzidine (BUMPHP-BZH2,VI) have been reported. These chelates have been prepared by the interaction of [MoO2 (acac)2] ( where acacH = acetylacetone) with the respective pyrazolone based Schiff base ligand in ethanol medium. The resulting chelates have been characterized on the basis of elemental analyses, molar conductance. Decomposition temperature, magnetic measurement, thermogravimetric analyses, 1H-NMR, IR and electronic spectral studies and have been found to contain cis-MO2 structure.
