Abstract: Metal complexes of Cr(lll), Mn(II), Fe(III), Co(Il), Ni(II), Cu(II), Zn(II), Cd (II) and Hg(II) with 4-butyl -1- (4-hydroxyphenyl) -2- phenyl-B. 5-pyrazolidinedione (oxyphenbutazone, OPB) have been synthesized and characterised. The IR spectral studies show that except for Hg(II), the ligand coordinates to the metal ion through the nontautomeric carbonyl group. In the case of Hg(Il) complex, both tautomeric and nontautomeric carbonyl groups coordinate to the two Hg atoms. This is supported by the NMR spectrum of the complex.
