Abstract

Of the known halides of chromium, molybdenum
and tungsten only about one-third have been studied by
X-ray structural techniques (see Table 1). The structures
reported for these halides can be divided into three
categories.
1. The two or three-dimensional lattice type is the
most common. The lattice usually contains MX6 octahedra
(M = Cr, Mo, W I X = halogen), the overall packing of
which gives the appropriate polymeric form of the halide.
Examples of this type are the di- and tri-halides of
chromium.
2, Molecular crystals are formed by some halides. Amongst
known structures this is confined at present to the
hexahalides, e.g., WC16.
3. Polynuclear complexes may be formed by some of the
halides, e.g. dimeric molybdenum pentachloride (MO2C110).
