The structure of the higherature monoclinic variety α-SrHfF6 (strontium hafnium hexafluoride) [and of isostructural α-SrZrF6 (strontium zirconium hexafluoride)] associates Hf2F12 bipolyhedra and SrF8 snub disphenoids, forming zigzag twisted [SrF6]n layers. The distribution of the Hf and Sr polyhedra forms a three-dimensional framework which can be related to the family of anion-excess ReO3-related superstructures. α-SrHfF6 corresponds to a new ABX6 type and is compared to the other main families already described. A partial amorphization of this structure is observed in samples quenched from the melt.The crystal structure of α-SrHfF6 corresponds to a new structure type in the ABX6 series. It associates Hf2F12 bipolyhedra and SrF8 snub disphenoids, forming zigzag twisted [SrF6]n layers.
