Zr P P P Rh
ZrRhP3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Zr(1) is bonded to six equivalent P(1) atoms to form corner-sharing ZrP6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.30 Å) and three longer (2.64 Å) Zr(1)-P(1) bond lengths. Rh(1) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. All Rh(1)-P(1) bond lengths are 3.25 Å. P(1) is bonded in a linear geometry to two equivalent Zr(1) and one Rh(1) atom.
