Fe2As- crystal types

Recently, the crystal structure of stoichiometric La2S4 was described by Dugue et al. (1978). It is a super-structure, with distortion, of the anti-Fe2As type the orthorhombic Pnma cell is a = 2ao, b - 2co, c = Oo. The structure is formed, as for all the polysulfides and polyselenides of the light lanthanides, by alternating sheets... [Pg.12]
