Materials Data on Rb2NiP2 by Materials Project

Rb2NiP2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent P2- atoms. There are four shorter (3.52 Å) and two longer (3.56 Å) Rb–P bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent P2- atoms. There are two shorter (3.42 Å) and four longer (3.72 Å) Rb–P bond lengths. Ni2+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent P2- atoms. All Ni–P bond lengths are 2.25 Å. P2- is bonded in a 9-coordinate geometry to six Rb1+, two equivalent Ni2+, and one P2- atom. The P–P bond length is 2.18 Å.
