The crystal structure described by Ru(CN)2 crystallizes in the tetragonal P4_2/mnm space group. Ru(1) is bonded to two equivalent C(1) and four equivalent N(1) atoms to form edge-sharing RuC2N4 octahedra. C(1) is bonded in a linear geometry to one Ru(1) and one N(1) atom. N(1) is bonded in a 3-coordinate geometry to two equivalent Ru(1) and one C(1) atom. is represented by the CIF file [CIF]
