The material described by Bi2(CN2)3 crystallizes in the trigonal R32 space group. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. Bi(1) is bonded to six equivalent N(1) atoms to form distorted edge-sharing BiN6 pentagonal pyramids. N(1) is bonded in a distorted trigonal planar geometry to one C(1) and two equivalent Bi(1) atoms. is represented by the CIF file [CIF]
