title: Materials Data on Sr2Re4H16C3(N2O7)3 by Materials Project

description: Sr2Re4C3H16(N2O7)3 crystallizes in the orthorhombic Fdd2 space group. The structure is two-dimensional and consists of four Sr2Re4C3H16(N2O7)3 sheets oriented in the (0, 0, 1) direction. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–2.81 Å. There are two inequivalent Re7+ sites. In the first Re7+ site, Re7+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Re–O bond distances ranging from 1.74–1.77 Å. In the second Re7+ site, Re7+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Re–O bond distances ranging from 1.74–1.77 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. There is one shorter (1.34 Å) and one longer (1.35 Å) C–N bond length. The C–O bond length is 1.28 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to two equivalent N3- and one O2- atom. Both C–N bond lengths are 1.34 Å. The C–O bond length is 1.28 Å. There are three 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. 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 O2- atom. The H–O bond length is 0.98 Å. 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 O2- atom. The H–O bond length is 0.99 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Re7+ atom. In the second O2- site, O2- is bonded in a water-like geometry to one Sr2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to two equivalent Sr2+ and one C4+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the seventh O2- site, O2- is bonded in a distorted linear geometry to one Sr2+ and one Re7+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Re7+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one Re7+ atom.
