Mn2OsN3 crystallizes in the orthorhombic Cmc2_1 space group. Mn(1) is bonded to one N(2) and three equivalent N(1) atoms to form distorted corner-sharing MnN4 trigonal pyramids. Os(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to three equivalent Mn(1) and one Os(1) atom. In the second N site, N(2) is bonded to two equivalent Mn(1) and two equivalent Os(1) atoms to form corner-sharing NMn2Os2 trigonal pyramids.
Mn2OsN3 crystallizes in the orthorhombic Cmc2_1 space group. Mn(1) is bonded to one N(2) and three equivalent N(1) atoms to form distorted corner-sharing MnN4 trigonal pyramids. The Mn(1)-N(2) bond length is 1.88 Å. There is one shorter (1.85 Å) and two longer (1.88 Å) Mn(1)-N(1) bond lengths. Os(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Os(1)-N(1) bond lengths are 2.00 Å. Both Os(1)-N(2) bond lengths are 2.00 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to three equivalent Mn(1) and one Os(1) atom. In the second N site, N(2) is bonded to two equivalent Mn(1) and two equivalent Os(1) atoms to form corner-sharing NMn2Os2 trigonal pyramids.
