MnOs2P crystallizes in the monoclinic Cm space group. Mn(1) is bonded in a single-bond geometry to four equivalent Os(2) and one P(1) atom. There are a spread of Mn(1)-Os(2) bond distances ranging from 2.39-2.90 Å. The Mn(1)-P(1) bond length is 1.19 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to one Os(2) and three equivalent P(1) atoms. The Os(1)-Os(2) bond length is 2.93 Å. There is one shorter (1.75 Å) and two longer (2.10 Å) Os(1)-P(1) bond lengths. In the second Os site, Os(2) is bonded in a 9-coordinate geometry to four equivalent Mn(1), one Os(1), and four equivalent Os(2) atoms. All Os(2)-Os(2) bond lengths are 2.83 Å. P(1) is bonded in a single-bond geometry to one Mn(1) and three equivalent Os(1) atoms.
