A new gadolinium ytterbium trifluoride has been grown for the first time by the Czochralski technique. Although GdF3 and YbF3 both present a high-temperature phase transition, the mixed compound Gd0.81Yb0.19F3 maintains its crystallographic structure upon cooling to room temperature. The grown crystal melts noncongruently at ∼1413 K, it is transparent and colourless, and it has a high density.

The title compound contains Na+ cations within both a six-sided tunnel and a large S-shaped tunnel formed by the manganese oxide framework. The unexpected location of a new Na+ site within the S-shaped tunnel accounts for the observation of an Na stoichiometry greater than 4.

Special and virtual issues

Acta Crystallographica Section C is planning special issues on

The Structural Chemistry of Homogeneous and Heterogeneous Catalysts

NMR Crystallography.

Full details are available on the special issues page.

The latest virtual issue, featuring Coordination polymers and with an introduction by Len Barbour, was published in July 2014.
