AgCN(AgNO3)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional and consists of two AgCN ribbons oriented in the (1, 0, 0) direction and one AgNO3 framework. In each AgCN ribbon, Ag1+ is bonded in a distorted linear geometry to one C4+ and one N+1.67+ atom. The Ag–C bond length is 2.05 Å. The Ag–N bond length is 2.10 Å. C4+ is bonded in a linear geometry to one Ag1+ and one N+1.67+ atom. The C–N bond length is 1.18 Å. N+1.67+ is bonded in a linear geometry to one Ag1+ and one C4+ atom. In the AgNO3 framework, there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ag–O bond distances ranging from 2.49–2.92 Å. In the second Ag1+ site, Ag1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ag–O bond distances ranging from 2.47–2.93 Å. There are two inequivalent N+1.67+ sites. In the first N+1.67+ site, N+1.67+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.26–1.28 Å. In the second N+1.67+ site, N+1.67+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.26 Å) and two longer (1.28 Å) N–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ag1+ and one N+1.67+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Ag1+ and one N+1.67+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag1+ and one N+1.67+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag1+ and one N+1.67+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ag1+ and one N+1.67+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag1+ and one N+1.67+ atom.
