The structure described by Cr(NiN)3 crystallizes in the hexagonal P6_3/m space group. Cr(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. N(1) is bonded in a 5-coordinate geometry to one Cr(1) and four equivalent Ni(1) atoms. is represented by the CIF file [CIF]
