The author's previous work on the application of Wigner's theory of the coreps of non-unitary groups to the Shubnikov groups (magnetic groups) is here considered in relation to crystal field theory. Both the splitting of the energy levels and the symmetry properties of the wave function are considered in magnetic point groups. Examples of 4'mm' and 4m'm' are studied.

Some initial work has recently been done (Cracknell 1966a) on the applicationof the theory of the corepresentations of non-unitary groups to the consideration ofthe splitting of atomic energy levels in a crystalline field possessing the mmetryof one of the magnetic point groups, or Shubnikov point groups. In that work onlythe situation of a strong rystalline field in the complete absence of spin

Abstract The electronic structure of dodecahedral octacyanides of molybdenum IV and V is described in terms of SCCC molecular orbitals. Five MO's resemble d orbitals of the central atom. The splitting of appropriate levels is almost exactly the same as that following from the crystal field theory for G4/G2 ~ 0.7. According to the theory stable Mo(CN)84- is dodecahedral and stable MO(CN)83- is antiprismatic. In the dodecahedron the A-type ligands are bonded more strongly than the B-type ligands.
