New Structural Units in Molybdenum Oxyfluoride Chemistry. -The structures of the new compounds (II)-(IV), (VI), and (VII) are determined by single crystal XRD. The Mo VI compound (II) and the reduced Mo V compound (III) crystallize in the space group C2/c with Z = 4. The isostructural Mo V compounds (IV) and (VI) crystallize in the space group Pmnn with Z = 2, and the Mo IV compound (VII) in the space group C2/c with Z = 8. -(ALDOUS, D. W.; LIGHTFOOT*, P.; J.
