Mn Cr Cd Cd
CrMnCd2 crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a 4-coordinate geometry to one Mn(1) and three equivalent Cd(1) atoms. The Cr(1)-Mn(1) bond length is 2.29 Å. There is one shorter (1.63 Å) and two longer (2.44 Å) Cr(1)-Cd(1) bond lengths. Mn(1) is bonded in a 2-coordinate geometry to one Cr(1) and one Cd(2) atom. The Mn(1)-Cd(2) bond length is 2.84 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 1-coordinate geometry to three equivalent Cr(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 2.02 Å. In the second Cd site, Cd(2) is bonded in a 2-coordinate geometry to one Mn(1) and one Cd(1) atom.
