Y2CoCl crystallizes in the monoclinic Cm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted bent 150 degrees geometry to one Y(2), four equivalent Y(1), and three equivalent Co(1) atoms. The Y(1)-Y(2) bond length is 2.14 Å. All Y(1)-Y(1) bond lengths are 3.31 Å. There is one shorter (3.31 Å) and two longer (3.79 Å) Y(1)-Co(1) bond lengths. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to one Y(1), four equivalent Y(2), and three equivalent Cl(1) atoms. All Y(2)-Y(2) bond lengths are 3.31 Å. There is one shorter (3.02 Å) and two longer (3.54 Å) Y(2)-Cl(1) bond lengths. Co(1) is bonded in a single-bond geometry to three equivalent Y(1) and one Cl(1) atom. The Co(1)-Cl(1) bond length is 0.33 Å. Cl(1) is bonded in a single-bond geometry to three equivalent Y(2) and one Co(1) atom.
