Materials Data on Rb4Ge9(H3N)5 by Materials Project
Rb4(NH3)5(Ge)9 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of thirty-six germanium molecules and two Rb4(NH3)5 sheets oriented in the (0, 0, 1) direction. In each Rb4(NH3)5 sheet, there are four inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to four N3- and three H+0.47- atoms. There are a spread of Rb–N bond distances ranging from 3.09–3.41 Å. There are a spread of Rb–H bond distances ranging from 3.07–3.28 Å. In the second Rb1+ site, Rb1+ is bonded in a bent 150 degrees geometry to one N3- and one H+0.47- atom. The Rb–N bond length is 2.98 Å. The Rb–H bond length is 3.01 Å. In the third Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to three N3- and four H+0.47- atoms. There are one shorter (3.18 Å) and two longer (3.25 Å) Rb–N bond lengths. There are a spread of Rb–H bond distances ranging from 3.04–3.24 Å. In the fourth Rb1+ site, Rb1+ is bonded in a 3-coordinate geometry to one N3- and two H+0.47- atoms. The Rb–N bond length is 3.13 Å. There are one shorter (2.90 Å) and one longer (3.05 Å) Rb–H bond lengths. There are five inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal non-coplanar geometry to two Rb1+ and three H+0.47- atoms. All N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a trigonal non-coplanar geometry to one Rb1+ and three H+0.47- atoms. All N–H bond lengths are 1.03 Å. In the third N3- site, N3- is bonded in a trigonal non-coplanar geometry to one Rb1+ and three H+0.47- atoms. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. In the fourth N3- site, N3- is bonded in a trigonal non-coplanar geometry to two Rb1+ and three H+0.47- atoms. All N–H bond lengths are 1.03 Å. In the fifth N3- site, N3- is bonded in a trigonal non-coplanar geometry to three Rb1+ and three H+0.47- atoms. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. There are fifteen inequivalent H+0.47- sites. In the first H+0.47- site, H+0.47- is bonded in a single-bond geometry to one Rb1+ and one N3- atom. In the second H+0.47- site, H+0.47- is bonded in a single-bond geometry to one N3- atom. In the third H+0.47- site, H+0.47- is bonded in a single-bond geometry to one Rb1+ and one N3- atom. In the fourth H+0.47- site, H+0.47- is bonded in a single-bond geometry to one N3- atom. In the fifth H+0.47- site, H+0.47- is bonded in a single-bond geometry to one Rb1+ and one N3- atom. In the sixth H+0.47- site, H+0.47- is bonded in a single-bond geometry to one Rb1+ and one N3- atom. In the seventh H+0.47- site, H+0.47- is bonded in a single-bond geometry to one N3- atom. In the eighth H+0.47- site, H+0.47- is bonded in a single-bond geometry to one Rb1+ and one N3- atom. In the ninth H+0.47- site, H+0.47- is bonded in a single-bond geometry to two Rb1+ and one N3- atom. In the tenth H+0.47- site, H+0.47- is bonded in a single-bond geometry to one N3- atom.
