The crystal structure described by Cr2(CN2)3 crystallizes in the trigonal R-3c space group. Cr(1) is bonded to six equivalent N(1) atoms to form edge-sharing CrN6 octahedra. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
