Materials Data on Rb3Cd(NO2)3 by Materials Project
Rb3Cd(NO2)3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Rb3Cd(NO2)3 cluster. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Rb–O bond distances ranging from 2.78–2.95 Å. In the second Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to three O2- atoms. There are a spread of Rb–O bond distances ranging from 2.62–2.92 Å. In the third Rb1+ site, Rb1+ is bonded in an L-shaped geometry to two O2- atoms. There are one shorter (2.66 Å) and one longer (2.76 Å) Rb–O bond lengths. Cd2+ is bonded in a single-bond geometry to one O2- atom. The Cd–O bond length is 2.04 Å. There are three inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) N–O bond length. In the second N+2.33+ site, N+2.33+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.29 Å) N–O bond length. In the third N+2.33+ site, N+2.33+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.23 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+ and one N+2.33+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Rb1+ and one Cd2+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Rb1+ and one N+2.33+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one N+2.33+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one N+2.33+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Rb1+ and one N+2.33+ atom.
