Abstract

Ce(RhP)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to eight Rh and eight P atoms. There are four shorter (3.19 Å) and four longer (3.21 Å) Ce–Rh bond lengths. There are four shorter (3.12 Å) and four longer (3.15 Å) Ce–P bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to four equivalent Ce and five P atoms. There are four shorter (2.35 Å) and one longer (2.36 Å) Rh–P bond lengths. In the second Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Ce and four equivalent P atoms. All Rh–P bond lengths are 2.47 Å. There are two inequivalent P sites. In the first P site, P is bonded in a 8-coordinate geometry to four equivalent Ce and four equivalent Rh atoms. In the second P site, P is bonded in a 9-coordinate geometry to four equivalent Ce and five Rh atoms.
