Crystal structure refinement of K2HfF6
Published/Copyright:
August 25, 2010
Abstract
K2HfF6 is monoclinic: a = 6.592(3), b = 11.485(5), c = 6.910(3) Å, β = 90.56(5)°, space group C2/c, Z = 4. The structure was refined to R = 0.0214 and Rw = 0.0270 by least-squares methods, using 780 unique observed reflections. K2HfF6 is isostructural with K2ZrF6. The structure consists of chains of [HfF8]-polyhedra. The coordination geometry around the Hf atom is a distorted bisdisphenoid (or triangulated dodecahedron) of symmetry 2. The [KF8]-polyhedra are intermediate between a square antiprism and a bicapped triangular prism.
