MnCdAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnCdAs clusters. Mn(1) is bonded in a single-bond geometry to one Cd(1) atom. The Mn(1)-Cd(1) bond length is 1.85 Å. Cd(1) is bonded in a single-bond geometry to one Mn(1) and one As(1) atom. The Cd(1)-As(1) bond length is 0.09 Å. As(1) is bonded in a single-bond geometry to one Cd(1) atom.
