title: A novel nonanuclear hafnium oxide-hydroxide-sulphate cluster crystallised from aqueous solution.
abstract: Single crystals of (NH4)14[Hf9O8(OH)6(SO4)14]·nH2O (1) were obtained by heating a sealed aqueous solution of HfOCl2·8H2O, (NH4)2SO4 and H2SO4 at 80 °C for 10 days. The discrete [Hf9O8(OH)6(SO4)14](14-) anionic clusters have no inter-cluster connectivity. This rare nonameric architecture has only been observed previously in two Bi(3+) oxo clusters.
