Mn Mn Cd As
Mn2CdAs is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mn2CdAs clusters. Mn(1) is bonded in a distorted single-bond geometry to one Cd(1) and one As(1) atom. The Mn(1)-Cd(1) bond length is 0.20 Å. The Mn(1)-As(1) bond length is 0.41 Å. Cd(1) is bonded in a distorted water-like geometry to two equivalent Mn(1) and one As(1) atom. The Cd(1)-As(1) bond length is 0.37 Å. As(1) is bonded in a 3-coordinate geometry to two equivalent Mn(1) and one Cd(1) atom.
