Abstract

Six quaternary rare-earth-containing sulphides RE₃MInS₇ (M=Fe, Co, Ni) have been prepared by reactions of the elements at 1050-1150 C. They are the first examples of chalcogenides RE₃MM'Ch₇ adopting related La₃CuSiS₇- or ordered Ce₃Al_1.67S₇-type structures in which the M' component is indium. They crystallize in the noncentrosymmetric hexagonal space group P6₃ with Z=2 and cell parameters in the ranges of a=9.95-10.15 Å and c=6.25-6.29 Å for RE₃FeInS₇ (RE=La-Pr), RE₃CoInS₇ (RE=La, Ce), and La₃NiInS₇. The crystal structure consists of parallel chains of face-sharing M-centred octahedra and stacks of In-centred tetrahedra, all pointing in the same polar direction, with seven-coordinate La atoms in the intervening spaces. X-ray photoelectron spectra support the valence assignments implied by the formulation (RE³⁺)₃(M²⁺)(In³+)(S^2-)₇. Magnetic measurements are suggestive of antiferromagnetic coupling between the M moments. Band structure calculations reveal that a band gap of 0.25 eV is present in La₃FeInS₇, whereas the increased electron count in La₃CoInS₇ and La₃NiInS₇ causes the Fermi level to cut narrow bands.
