Fluoride crystal structures. Part XVIII. Dipotassium catena-µ-fluoro-difluoro-µ-sulphato-manganate(III)

Abstract

Crystals of the title compound are orthorhombic, space group Pnab, a= 7·26, b= 8·45, c= 10·77 Å. The structure was refined by three-dimensional least-squares methods to R 0·064 for 390 reflections. In the crystal manganese atoms are linked through trans-bridging fluorine atoms and bridging sulphate groups to give an endless chain arrangement parallel to a, with a distorted octahedral co-ordination of the manganese atoms. There are two Mn–F(terminal) distances of 1·82, two Mn–F(bridge) of 2·04, and two Mn–O of 2·01 Å, giving the opposite type of distortion in the octahedron to that usually found.
