Materials Data on CuH3(NO2)3 by Materials Project
Cu(NO3)2NH3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four ammonia molecules and one Cu(NO3)2 sheet oriented in the (1, 0, 0) direction. In the Cu(NO3)2 sheet, Cu2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.99–2.37 Å. There are two inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.32 Å. In the second N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.24 Å) and two longer (1.29 Å) N–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one N+2.33+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one N+2.33+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one N+2.33+ atom.
