Y(MnCo)6 crystallizes in the orthorhombic Immm space group. Y(1) is bonded in a 20-coordinate geometry to two equivalent Mn(1), two equivalent Mn(2), four equivalent Mn(3), four equivalent Co(2), and eight equivalent Co(1) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 14-coordinate geometry to one Y(1), one Mn(1), two equivalent Mn(3), four equivalent Mn(2), two equivalent Co(2), and four equivalent Co(1) atoms. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to one Y(1), one Mn(2), two equivalent Mn(3), four equivalent Mn(1), two equivalent Co(2), and four equivalent Co(1) atoms. In the third Mn site, Mn(3) is bonded in a 12-coordinate geometry to two equivalent Y(1), two equivalent Mn(1), two equivalent Mn(2), two equivalent Co(2), and four equivalent Co(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Y(1), two equivalent Mn(1), two equivalent Mn(2), two equivalent Mn(3), two equivalent Co(1), and two equivalent Co(2) atoms to form a mixture of distorted edge, face, and corner-sharing CoY2Mn6Co4 cuboctahedra. In the second Co site, Co(2) is bonded to two equivalent Y(1), two equivalent Mn(1), two equivalent Mn(2), two equivalent Mn(3), and four equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing CoY2Mn6Co4 cuboctahedra.
