Y Mn Mn Cd
YMn2Cd crystallizes in the monoclinic Cm space group. Y(1) is bonded in a 2-coordinate geometry to one Mn(1), one Mn(2), and two equivalent Cd(1) atoms. The Y(1)-Mn(1) bond length is 1.57 Å. The Y(1)-Mn(2) bond length is 1.53 Å. There is one shorter (3.44 Å) and one longer (3.58 Å) Y(1)-Cd(1) bond length. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 2-coordinate geometry to one Y(1), one Mn(2), and one Cd(1) atom. The Mn(1)-Mn(2) bond length is 0.87 Å. The Mn(1)-Cd(1) bond length is 3.42 Å. In the second Mn site, Mn(2) is bonded in a 2-coordinate geometry to one Y(1), one Mn(1), and one Cd(1) atom. The Mn(2)-Cd(1) bond length is 3.42 Å. Cd(1) is bonded to two equivalent Y(1), one Mn(1), one Mn(2), and four equivalent Cd(1) atoms to form a mixture of corner and edge-sharing CdY2Mn2Cd4 hexagonal bipyramids. All Cd(1)-Cd(1) bond lengths are 3.38 Å.
