Materials Data on Pr(PRh)2 by Materials Project

Abstract

Pr(RhP)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to eight Rh and eight P atoms. There are four shorter (3.21 Å) and four longer (3.25 Å) Pr–Rh bond lengths. There are four shorter (3.14 Å) and four longer (3.18 Å) Pr–P bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Pr and four equivalent P atoms. All Rh–P bond lengths are 2.48 Å. In the second Rh site, Rh is bonded in a 9-coordinate geometry to four equivalent Pr and five P atoms. There are four shorter (2.36 Å) and one longer (2.41 Å) Rh–P bond lengths. There are two inequivalent P sites. In the first P site, P is bonded in a 8-coordinate geometry to four equivalent Pr and four equivalent Rh atoms. In the second P site, P is bonded in a 9-coordinate geometry to four equivalent Pr and five Rh atoms.
