RuCu2P is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuCu2P clusters. Ru(1) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. Both Ru(1)-Cu(1) bond lengths are 0.84 Å. Cu(1) is bonded in an L-shaped geometry to one Ru(1) and one P(1) atom. The Cu(1)-P(1) bond length is 0.84 Å. P(1) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms.
