Y In W W
YW2In crystallizes in the trigonal R3m space group. Y(1) is bonded in a 8-coordinate geometry to four equivalent W(1), six equivalent W(2), and four equivalent In(1) atoms. There is one shorter (3.01 Å) and three longer (3.04 Å) Y(1)-W(1) bond lengths. There are three shorter (3.48 Å) and three longer (3.53 Å) Y(1)-W(2) bond lengths. There are three shorter (3.01 Å) and one longer (3.11 Å) Y(1)-In(1) bond length. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent Y(1) and four equivalent W(2) atoms to form distorted WY4W4 tetrahedra that share corners with twelve equivalent W(2)Y6In4W4 tetrahedra, edges with twelve equivalent W(1)Y4W4 tetrahedra, and faces with four equivalent W(2)Y6In4W4 tetrahedra. There is one shorter (3.01 Å) and three longer (3.04 Å) W(1)-W(2) bond lengths. In the second W site, W(2) is bonded to six equivalent Y(1), four equivalent W(1), and four equivalent In(1) atoms to form distorted WY6In4W4 tetrahedra that share corners with six equivalent W(2)Y6In4W4 tetrahedra, corners with twelve equivalent W(1)Y4W4 tetrahedra, faces with four equivalent W(1)Y4W4 tetrahedra, and faces with twelve equivalent W(2)Y6In4W4 tetrahedra. There is one shorter (3.01 Å) and three longer (3.04 Å) W(2)-In(1) bond lengths. In(1) is bonded in a distorted body-centered cubic geometry to four equivalent Y(1) and four equivalent W(2) atoms.
