The structure described by Lu2(CN2)3 crystallizes in the trigonal R-3c space group. Lu(1) is bonded to six equivalent N(1) atoms to form distorted edge-sharing LuN6 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 Lu(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
