Enthalpies of formation of alkali-metal hexachloro-zirconates and -hafnates

Abstract

Enthalpies of reaction have been determined by solution calorimetry for the process (i) where M′= Na, K, or Cs 2 M′Cl(c)+ MCl4(c) M′2[MCl6](c)(i) and M = Zr or Hf. Heats of formation for the complexes, ΔHf(298 K), have been calculated using mean values of ΔHf for MCl4 taken from the literature. The reaction is marginally more favourable when M = Hf but both ZrCl4 and HfCl4 are somewhat better acceptors of chloride ion than is NbCl4 and both are markedly better acceptors than SnCl4.
