Hf P Ru Ru
HfRu2P is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfRu2P clusters. Hf(1) is bonded in a single-bond geometry to two equivalent Ru(1) and one P(1) atom. Both Hf(1)-Ru(1) bond lengths are 1.14 Å. The Hf(1)-P(1) bond length is 0.58 Å. Ru(1) is bonded in a 2-coordinate geometry to one Hf(1) and one Ru(1) atom. The Ru(1)-Ru(1) bond length is 0.58 Å. P(1) is bonded in a single-bond geometry to one Hf(1) atom.
