Materials Data on CdRe2H8C2(N2O5)2 by Materials Project
Re2CdC2H8(N2O5)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two Re2CdC2H8(N2O5)2 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Re7+ sites. In the first Re7+ site, Re7+ is bonded to four O2- atoms to form ReO4 tetrahedra that share corners with two equivalent CdO6 octahedra. The corner-sharing octahedra tilt angles range from 37–42°. There are a spread of Re–O bond distances ranging from 1.74–1.77 Å. In the second Re7+ site, Re7+ is bonded to four O2- atoms to form ReO4 tetrahedra that share corners with two equivalent CdO6 octahedra. The corner-sharing octahedra tilt angles range from 30–44°. There are a spread of Re–O bond distances ranging from 1.74–1.77 Å. Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with four ReO4 tetrahedra. There are a spread of Cd–O bond distances ranging from 2.24–2.40 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to two N3- and one O2- atom. Both C–N bond lengths are 1.34 Å. The C–O bond length is 1.29 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to two N3- and one O2- atom. Both C–N bond lengths are 1.35 Å. The C–O bond length is 1.28 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the second N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the third N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.01 Å. In the fourth N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.01 Å) and one longer (1.02 Å) N–H bond length. There are eight 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 N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are ten inequivalent O2- sites.
