Re Ni P P P P
ReNiP4 crystallizes in the trigonal R3m space group. Re(1) is bonded in a distorted single-bond geometry to one Ni(1), three equivalent P(1), and three equivalent P(2) atoms. The Re(1)-Ni(1) bond length is 1.48 Å. All Re(1)-P(1) bond lengths are 2.24 Å. All Re(1)-P(2) bond lengths are 3.05 Å. Ni(1) is bonded to one Re(1), three equivalent P(1), and three equivalent P(2) atoms to form distorted corner-sharing NiReP6 trigonal pyramids. All Ni(1)-P(1) bond lengths are 2.01 Å. All Ni(1)-P(2) bond lengths are 3.05 Å. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 9-coordinate geometry to three equivalent Re(1), three equivalent Ni(1), and three equivalent P(1) atoms. All P(2)-P(1) bond lengths are 2.45 Å. In the second P site, P(1) is bonded in a 4-coordinate geometry to one Re(1), one Ni(1), one P(2), and two equivalent P(1) atoms. Both P(1)-P(1) bond lengths are 1.42 Å.
