Materials Data on CuH8C4(NO3)2 by Materials Project
CuC4H8(NO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one CuC4H8(NO3)2 sheet oriented in the (0, 0, 1) direction. Cu2+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.95–2.58 Å. There are two inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a trigonal planar geometry to one N3-, one H1+, and one O2- atom. The C–N bond length is 1.33 Å. The C–H bond length is 1.11 Å. The C–O bond length is 1.25 Å. In the second C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. Both C–O bond lengths are 1.27 Å. N3- is bonded in a trigonal planar geometry to one C2+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Cu2+ and one C2+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one C2+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one C2+ atom.
