The material described by Ru(CN)2 crystallizes in the orthorhombic Pbca space group. Ru(1) is bonded to one C(1), one C(2), two equivalent N(1), and two equivalent N(2) atoms to form a mixture of corner and edge-sharing RuC2N4 octahedra. The corner-sharing octahedral tilt angles are 55°. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Ru(1) and one N(1) atom. In the second C site, C(2) is bonded in a linear geometry to one Ru(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(2) is bonded in a distorted trigonal planar geometry to two equivalent Ru(1) and one C(2) atom. In the second N site, N(1) is bonded in a distorted trigonal planar geometry to two equivalent Ru(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
