Molybdenum(VI), Uranium(VI) and Vanadium(V) Complexes of 4-Acylbis(L-Phenyl-3-Methylpyrazolone-5): Synthesis and Spectroscopic Characterization
The synthesis and characterization of metal complexes of 4-adipoyl and 4-sebacoyl derivatives of bis(l-phenyl-3-methylpyrazolone-5) with Mo(VI), U(VI) and V(V) are reported. Analytical and spectroscopic data show that the complexes are neutral and conform to a general empirical formula MO 2 (L) a (H...
