K Mn Cr Cd
KCrMnCd crystallizes in the trigonal R3m space group. K(1) is bonded in a 1-coordinate geometry to one Cr(1), three equivalent Mn(1), and three equivalent Cd(1) atoms. The K(1)-Cr(1) bond length is 2.45 Å. All K(1)-Mn(1) bond lengths are 3.11 Å. All K(1)-Cd(1) bond lengths are 3.04 Å. Cr(1) is bonded in a 1-coordinate geometry to one K(1), three equivalent Mn(1), and one Cd(1) atom. All Cr(1)-Mn(1) bond lengths are 3.04 Å. The Cr(1)-Cd(1) bond length is 2.45 Å. Mn(1) is bonded in a 10-coordinate geometry to three equivalent K(1), three equivalent Cr(1), and four equivalent Cd(1) atoms. There is one shorter (2.45 Å) and three longer (3.41 Å) Mn(1)-Cd(1) bond lengths. Cd(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Cr(1), and four equivalent Mn(1) atoms.
