Donor System

A new series of oxovanadium(IV) chelates containing bi-and tridentate pyrazol-5-one azo derivatives ligands of the type (I) [VO(L)2] and (2) [VO(L)(H2O)] have been prepared and characterized by elementary analysis, IR, electronic spectra, conductance measurements, and molecular weights. The ligands coordinate through (O-N) donor system as monobasic and bidentate (HL) for the first type and through (0-N-O) donor system as dibasic and tridentate (H2L) for the second type of complexes. The molecular weights, the presence of the (V=O) stretching band around 950 cm -1, and the visible spectra suggest a monomeric penta-coordinated structure for these complexes.
