Mn Co Os Os
MnOs2Co is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnOs2Co clusters. Mn(1) is bonded in a 3-coordinate geometry to two equivalent Os(1) and one Co(1) atom. Both Mn(1)-Os(1) bond lengths are 0.86 Å. The Mn(1)-Co(1) bond length is 0.74 Å. Os(1) is bonded in a 3-coordinate geometry to one Mn(1), one Os(1), and one Co(1) atom. The Os(1)-Os(1) bond length is 0.74 Å. The Os(1)-Co(1) bond length is 0.86 Å. Co(1) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Os(1) atoms.
