Materials Data on KAg(CN)2 by Materials Project
KAg(CN)2 is Potassium Silver Cyanide structured and crystallizes in the trigonal P-31c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six equivalent N3- atoms to form edge-sharing KN6 octahedra. There are three shorter (2.86 Å) and three longer (2.98 Å) K–N bond lengths. In the second K1+ site, K1+ is bonded to six equivalent N3- atoms to form edge-sharing KN6 octahedra. All K–N bond lengths are 2.92 Å. Ag1+ is bonded in a linear geometry to two equivalent C2+ atoms. Both Ag–C bond lengths are 2.05 Å. C2+ is bonded in a linear geometry to one Ag1+ and one N3- atom. The C–N bond length is 1.17 Å. N3- is bonded in a 4-coordinate geometry to three K1+ and one C2+ atom.
