Abstract
The reactions of tetra(isopropoxy)hafniumiso-propanol, Hf(OPri)4 · PriOH with monofunctional bidentate (MH) and bifunctional tridentate (BH2) benzoyl hydrazones (derived from the condensation of benzoyl hydrazine with aldehydes/ ketones) in different molar ratios have been carried out in refluxing benzene. Products of the type, Hf(OPri)4−n(M)n and Hf(OPri)4−2n(B)n (where n=1 to 4) were obtained and characterized on the basis of elemental analyses, electrical conductance measurements, and spectral (infrared, electronic and1H n.m.r.) data.
