ReNiP2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReNiP2 clusters. Re(1) is bonded in a 2-coordinate geometry to one P(1) and one P(2) atom. The Re(1)-P(1) bond length is 1.97 Å. The Re(1)-P(2) bond length is 1.85 Å. Ni(1) is bonded in a single-bond geometry to one P(2) atom. The Ni(1)-P(2) bond length is 1.08 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Re(1) atom. In the second P site, P(2) is bonded in a distorted single-bond geometry to one Re(1) and one Ni(1) atom.
