Sc Mn As
ScMnAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScMnAs clusters. Sc(1) is bonded in a single-bond geometry to one Mn(1) atom. The Sc(1)-Mn(1) bond length is 0.08 Å. Mn(1) is bonded in a linear geometry to one Sc(1) and one As(1) atom. The Mn(1)-As(1) bond length is 0.11 Å. As(1) is bonded in a single-bond geometry to one Mn(1) atom.
