Abstract

The reactions of Cp2HfCl2 with some higher monocarboxylic acids having straight chains, caprylic (C8H16O2), lauric (C12H24O2), myristic (C14H28O2), palmitic (C16H32O2), stearic (C18H36O2), and behenic (C22H44O2) acid, have been studied in anhydrous tetrahydrofuran in 1:1 and 1:2 molar ratios, respectively. The reaction products isolated, of types Cp2Hf(L)Cl, CpHf(L)2Cl (LH represents different carboxylic acids), have been characterised by conductivity and magnetic susceptibility measurements and spectral (infrared, electronic, 1HNMR and 13C NMR) data. The bonding of the carboxylato ligand in these complexes has been discussed and plausible structures have been established.
