MgOsN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Os(1)N4 tetrahedra. Os(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form OsN4 tetrahedra that share corners with four equivalent Os(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Os(1) atoms to form distorted corner-sharing NMg2Os2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Os(1) atoms to form corner-sharing NMg2Os2 tetrahedra.

Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Os(1)N4 tetrahedra. There is one shorter (2.08 Å) and one longer (2.15 Å) Mg(1)-N(1) bond length. There is one shorter (2.08 Å) and one longer (2.11 Å) Mg(1)-N(2) bond length. Os(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form OsN4 tetrahedra that share corners with four equivalent Os(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There is one shorter (1.91 Å) and one longer (2.02 Å) Os(1)-N(1) bond length. There is one shorter (1.94 Å) and one longer (1.99 Å) Os(1)-N(2) bond length. There are two inequivalent N sites.
