Abstract

The new sulfides Y₃Ni_0.5SiS₇, Sm₃Ni_0.5SiS₇, and La₃Ni_0.5SiS₇ exist in the quasi-ternary systems Y₂S₃ – NiS – SiS₂, Sm₂S₃ – NiS – SiS₂, and La₂S₃ – NiS – SiS₂, respectively, for which the isothermal sections at 770 K were investigated. The crystal structure of the sulfides was determined by the X-ray powder method. It belongs to the La₃Mn_0.5SiS₇ structure type (S.G. Р6₃; Pearson symbol hP23), with the lattice parameters а = 0.97643(4) nm; с = 0.56377(4) nm (Y₃Ni_0.5SiS₇), а = 0.99599(8) nm; с = 0.56583(5) nm (Sm₃Ni_0.5SiS₇), and а = 1.02830(6) nm; с = 0.57412(4) nm (La₃Ni_0.5SiS₇). The structure of obtained sulfides is as follows: Y, Sm, and La atoms are located in the 6с site and center trigonal prisms with two additional S atoms. Ni atoms occupy the 2а site (0.5 occupancy) and have octahedral surrounding of S atoms. The coordination number of Si atoms (the 2b site) is 4. The Ni-centered octahedra form infinite chains [Ni 6S]_n.
