Materials Data on RbH2N by Materials Project
RbNH2 crystallizes in the monoclinic P2_1/m space group. The structure is two-dimensional and consists of one RbNH2 sheet oriented in the (0, 0, 1) direction. Rb1+ is bonded in a 1-coordinate geometry to three equivalent N3- and four equivalent H1+ atoms. There are one shorter (2.93 Å) and two longer (3.06 Å) Rb–N bond lengths. There are two shorter (2.87 Å) and two longer (2.97 Å) Rb–H bond lengths. N3- is bonded in a distorted water-like geometry to three equivalent Rb1+ and two equivalent H1+ atoms. Both N–H bond lengths are 1.03 Å. H1+ is bonded in a single-bond geometry to two equivalent Rb1+ and one N3- atom.
