Os2(CN2)3 crystallizes in the monoclinic C2/m space group. Os(1) is bonded to one N(3), two equivalent N(1), and three equivalent N(2) atoms to form edge-sharing OsN6 octahedra. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. In the second C site, C(2) is bonded in a linear geometry to two equivalent N(3) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to two equivalent Os(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Os(1) and one C(1) atom. In the third N site, N(3) is bonded in a linear geometry to one Os(1) and one C(2) atom.
