Co2YIn crystallizes in the orthorhombic Pmma space group. Y(1) is bonded in a 13-coordinate geometry to three equivalent Co(2), four equivalent Co(1), and six equivalent In(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent Y(1), two equivalent Co(1), four equivalent Co(2), and two equivalent In(1) atoms to form a mixture of face, corner, and edge-sharing CoY4In2Co6 cuboctahedra. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), four equivalent Co(1), and two equivalent In(1) atoms. In(1) is bonded in a 12-coordinate geometry to six equivalent Y(1), two equivalent Co(1), two equivalent Co(2), and two equivalent In(1) atoms.
Co2YIn crystallizes in the orthorhombic Pmma space group. Y(1) is bonded in a 13-coordinate geometry to three equivalent Co(2), four equivalent Co(1), and six equivalent In(1) atoms. There is one shorter (2.65 Å) and two longer (2.83 Å) Y(1)-Co(2) bond lengths. All Y(1)-Co(1) bond lengths are 3.09 Å. There are four shorter (3.23 Å) and two longer (3.31 Å) Y(1)-In(1) bond lengths. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent Y(1), two equivalent Co(1), four equivalent Co(2), and two equivalent In(1) atoms to form a mixture of face, corner, and edge-sharing CoY4In2Co6 cuboctahedra. Both Co(1)-Co(1) bond lengths are 2.49 Å. All Co(1)-Co(2) bond lengths are 2.45 Å. Both Co(1)-In(1) bond lengths are 2.78 Å. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), four equivalent Co(1), and two equivalent In(1) atoms. Both Co(2)-In(1) bond lengths are 2.71 Å. In(1) is bonded in a 12-coordinate geometry to six equivalent Y(1), two equivalent Co(1), two equivalent Co(2), and two equivalent In(1) atoms. Both In(1)-In(1) bond lengths are 3.30 Å.
