NbRhP4 crystallizes in the trigonal R3m space group. Nb(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), three equivalent P(1), and three equivalent P(2) atoms. All Nb(1)-Rh(1) bond lengths are 3.03 Å. All Nb(1)-P(1) bond lengths are 2.59 Å. All Nb(1)-P(2) bond lengths are 2.89 Å. Rh(1) is bonded in a 13-coordinate geometry to four equivalent Nb(1), three equivalent P(2), and six equivalent P(1) atoms. All Rh(1)-P(2) bond lengths are 2.91 Å. There are three shorter (2.61 Å) and three longer (2.62 Å) Rh(1)-P(1) bond lengths. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to one Nb(1), two equivalent Rh(1), one P(2), and two equivalent P(1) atoms. The P(1)-P(2) bond length is 2.23 Å. Both P(1)-P(1) bond lengths are 1.29 Å. In the second P site, P(2) is bonded in a 9-coordinate geometry to three equivalent Nb(1), three equivalent Rh(1), and three equivalent P(1) atoms.
