Materials Data on Ag2CN2 by Materials Project
Ag2NCN is Potassium Silver Cyanide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four N3- atoms. There are a spread of Ag–N bond distances ranging from 2.19–2.89 Å. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent N3- atoms. Both Ag–N bond lengths are 2.15 Å. In the third Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent N3- atoms. Both Ag–N bond lengths are 2.17 Å. C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.21 Å) and one longer (1.27 Å) C–N bond length. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to three Ag1+ and one C4+ atom to form corner-sharing NAg3C tetrahedra. In the second N3- site, N3- is bonded in a 1-coordinate geometry to three equivalent Ag1+ and one C4+ atom.
