Abstract

(Ag(NO3)2)2N2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four ammonia molecules and two Ag(NO3)2 sheets oriented in the (0, 0, 1) direction. In each Ag(NO3)2 sheet, Ag1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.19–2.91 Å. There are two inequivalent N+3.67+ sites. In the first N+3.67+ site, N+3.67+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.22 Å) and two longer (1.29 Å) N–O bond length. In the second N+3.67+ site, N+3.67+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.29 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Ag1+ and one N+3.67+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+ and one N+3.67+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ag1+ and one N+3.67+ atom. In the fourth O2- site, O2- is bonded in a distorted L-shaped geometry to one Ag1+ and one N+3.67+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one N+3.67+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ag1+ and one N+3.67+ atom.
