Abstract

DURING an investigation of samarium–germanium compounds of composition near Sm5Ge3, X-ray powder diffraction photographs indicated additional lines which could not be indexed on the basis of the hexagonal unit cell established for Sm5Ge3 by Gladyshevskii1. Investigations of single crystals showed the phase to be orthorhombic and of a new structure-type. An analysis of the crystal structure2 showed the stoichiometry to be Sm5Ge4.
