Abstract
Crystals of antimony trifluoride are orthorhombic, space group C2cm, a= 4·95, b= 7·46, c= 7·26 Å, as previously reported. The structure was refined by three-dimensional least-squares methods, to R 0·072 for 370 reflections. Each antimony atom has three close fluorine neighbours with mean Sb–F distances 1·92 Å. These SbF3 units are then linked through three fluorine bridges (SbF 2·61 Å) to form a three-dimensional network, with a much distorted octahedral co-ordination around the antimony atom.Keywords
