Materials Data on Rb3BP2 by Materials Project
Rb3BP2 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two Rb3BP2 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to two equivalent P3- atoms. There are one shorter (3.47 Å) and one longer (3.67 Å) Rb–P bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to four equivalent P3- atoms. There are two shorter (3.57 Å) and two longer (3.63 Å) Rb–P bond lengths. B3+ is bonded in a linear geometry to two equivalent P3- atoms. Both B–P bond lengths are 1.78 Å. P3- is bonded in a 1-coordinate geometry to four Rb1+ and one B3+ atom.
