Sr3GaSb3 und Sr3InP3, zwei neue Zintlphasen mit komplexen Anionen / Sr3GaSb3 and Sr3InP3, Two New Zintl Phases with Complex Anions

Abstract

Abstract The new compound Sr3GaSb3 crystallizes in the monoclinic system, space group P21/n (No. 14) with the lattice constants: a = 1176.2(4) pm, b = 1450.9(5) pm, c = 1174.9(4) pm, β = 110.0(1)°. In the structure distorted GaSb4 tetrahedra are connected by common corners, to give strands with groups of four tetrahedra as the repeating unit. The new compound Sr3InP, crystallizes in the orthorhombic system, space group Pnma (No. 62) with the lattice constants: a = 1280.9(5) pm, b = 433.0(2) pm, c =1386.6(5) pm. In the structure distorted InP4 tetrahedra are connected by common corners, to give strands with one tetrahedron as the repeating unit. Both compounds are Zintl phases.
