Abstract
WIr is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. W is bonded to four equivalent W and eight equivalent Ir atoms to form WIr8W4 cuboctahedra that share corners with eight equivalent IrIr4W8 cuboctahedra, corners with ten equivalent WIr8W4 cuboctahedra, edges with six equivalent WIr8W4 cuboctahedra, edges with twelve equivalent IrIr4W8 cuboctahedra, faces with eight equivalent IrIr4W8 cuboctahedra, and faces with twelve equivalent WIr8W4 cuboctahedra. There are two shorter (2.78 Å) and two longer (2.80 Å) W–W bond lengths. There are a spread of W–Ir bond distances ranging from 2.75–2.82 Å. Ir is bonded to eight equivalent W and four equivalent Ir atoms to form IrIr4W8 cuboctahedra that share corners with eight equivalent WIr8W4 cuboctahedra, corners with ten equivalent IrIr4W8 cuboctahedra, edges with six equivalent IrIr4W8 cuboctahedra, edges with twelve equivalent WIr8W4 cuboctahedra, faces with eight equivalent WIr8W4 cuboctahedra, and faces with twelve equivalent IrIr4W8 cuboctahedra. There are two shorter (2.78 Å) and two longer (2.82 Å) Ir–Ir bond lengths.
