Abstract
Crystals of molybdenum oxide tetrafluoride are monoclinic, space group P21/c, a= 5·50, b= 16·98, c= 7·84 Å, β= 91·7°. The structure was refined by three-dimensional least-squares methods, the final R being 0·102 for 1909 independent reflections. In the crystal, octahedrally co-ordinated units are linked into endless chains by cis-bridging fluorine atoms. The fluorine bridge is asymmetric, but the octahedra formed by the light atoms are almost undistorted, with the molybdenum atoms displaced from the centres of these octahedra, towards the terminal oxygen atoms.Keywords
