“…MnBi has been reported to crystallize in an orthorhombic arrangement. Only X-ray powder data are available and in the two studies found (G6bel et aL, 1976;Andresen et al, 1972) all atomic positions are partially occupied, some to more than 100%! The Fe-Ge system contains a complex B8 region; Fe2Ge is reported as simple Ni2ln by Kim & Kang (1989), Fe3Ge2 has been reported as a badly disordered type structure of its own (Malaman et aL, 1980) and as the Pd13TI9 structure (Panday & Schubert, 1969), FesGe3 has been ascribed a simple Ni2In-type structure, either by disordered partial occupancy of the 2(d) position (Kanematsu et al, 1963) or by total disordering of all constituent atoms (Castelliz, 1953;Bara et al, 1981); Fe13Ge8 is a structure type of its own (Malaman et aL, 1980).…”
