The structure described by Cr2AgN3 crystallizes in the trigonal P3_121 space group. Cr(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. Ag(1) is bonded in a 10-coordinate geometry to six equivalent Ag(1) and four equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to six equivalent Cr(1) atoms to form distorted edge-sharing NCr6 octahedra. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Cr(1) and two equivalent Ag(1) atoms. is represented by the CIF file [CIF]
