Mn As Os Os
MnOs2As crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnOs2As cluster. Mn(1) is bonded in a distorted linear geometry to one Os(1) and one Os(2) atom. The Mn(1)-Os(1) bond length is 1.24 Å. The Mn(1)-Os(2) bond length is 1.85 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a linear geometry to one Mn(1) and one As(1) atom. The Os(1)-As(1) bond length is 0.03 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Mn(1) atom. As(1) is bonded in a single-bond geometry to one Os(1) atom.
