Materials Data on IrW by Materials Project

Abstract

WIr crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. W is bonded to six equivalent W and six equivalent Ir atoms to form WIr6W6 cuboctahedra that share corners with eighteen equivalent WIr6W6 cuboctahedra, edges with six equivalent WIr6W6 cuboctahedra, edges with twelve equivalent IrIr6W6 cuboctahedra, faces with eight equivalent WIr6W6 cuboctahedra, and faces with twelve equivalent IrIr6W6 cuboctahedra. All W–W bond lengths are 2.81 Å. All W–Ir bond lengths are 2.77 Å. Ir is bonded to six equivalent W and six equivalent Ir atoms to form IrIr6W6 cuboctahedra that share corners with eighteen equivalent IrIr6W6 cuboctahedra, edges with six equivalent IrIr6W6 cuboctahedra, edges with twelve equivalent WIr6W6 cuboctahedra, faces with eight equivalent IrIr6W6 cuboctahedra, and faces with twelve equivalent WIr6W6 cuboctahedra. All Ir–Ir bond lengths are 2.81 Å.
