Ru2NiP crystallizes in the monoclinic Cm space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Ni(1) and one P(1) atom. The Ru(1)-Ni(1) bond length is 2.83 Å. The Ru(1)-P(1) bond length is 0.11 Å. In the second Ru site, Ru(2) is bonded in a distorted linear geometry to one Ni(1) and one P(1) atom. The Ru(2)-Ni(1) bond length is 2.83 Å. The Ru(2)-P(1) bond length is 2.15 Å. Ni(1) is bonded to one Ru(1), one Ru(2), and six equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing NiNi6Ru2 hexagonal bipyramids. All Ni(1)-Ni(1) bond lengths are 2.79 Å. P(1) is bonded in a single-bond geometry to one Ru(1) and one Ru(2) atom.
