A new quaternary rare-earth sulfide,Cs0.75(6)Er4.43(5)In3.32(6)S12(1),is discovered by high temperature solid state reactions with a slight excess of CsCl flux.The structure is characterized by single-crystal X-ray diffraction data,while crystallizes in hexagonal space group P63/m(No.176)with a=12.0329(6),c=3.8693(5),V=485.18(7)3,Z=1,Mr=1606.57,Dc=5.499 g/cm3,μ=25.457 mm-1,F(000)=752,the final R=0.0337 and wR=0.0904 for 328observed reflections with I>2σ(I).Its structure features a three-dimensional framework with hexagonal channels that are centered by Cs cations.Such channels are formed by double chains of edge-sharing M(1)S6(M(1)=Er(1)/In(1))octahedra and single chains of Er(2)S6triprism interconnected by corner-sharing.The syntheses,single-crystal analyses,optical band gap and magnetic property are reported.
A new quaternary rare earth sulfide, Cs0.75 (6) Er4.43 (5) In3.32 (6) S12 (1), is discovered by high temperature solid state reactions with a slight excess of CsCl flux. Structure is characterized by single-crystal X-ray diffraction data, while crystallizes in hexagonal space group P63 / m (No.176) with a = 12.0329 (6), c = 3.8693 (5), V = 485.18 (7) 1 = Mr = 1606.57, Dc = 5.499 g / cm3, μ = 25.457 mm-1, F (000) = 752, the final R = 0.0337 and wR = 0.0904 for 328observed reflections with I> 2σ (I) a three-dimensional framework with hexagonal channels that are centered by Cs cations. Shu channels are formed by double chains of edge-sharing M (1) S6 (M (1) = Er (1) / In chains of Er (2) S6triprism interconnected by corner-sharing. The syntheses, single-crystal analyzes, optical band gap and magnetic properties are reported.
