The material described by Yb2(CN2)3 crystallizes in the trigonal R-3c space group. Yb(1) is bonded to six equivalent N(1) atoms to form edge-sharing YbN6 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 Yb(1) and one C(1) atom. is represented by the CIF file [CIF]
