Pt2Ru crystallizes in the trigonal R3 space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to three equivalent Ru(2) and one Pt(4) atom. All Ru(1)-Ru(2) bond lengths are 0.23 Å. The Ru(1)-Pt(4) bond length is 2.56 Å. In the second Ru site, Ru(2) is bonded in a 3-coordinate geometry to one Ru(1), two equivalent Ru(2), and one Pt(2) atom. Both Ru(2)-Ru(2) bond lengths are 0.23 Å. The Ru(2)-Pt(2) bond length is 2.94 Å. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 3-coordinate geometry to one Pt(4) and two equivalent Pt(2) atoms. The Pt(1)-Pt(4) bond length is 2.62 Å. Both Pt(1)-Pt(2) bond lengths are 2.62 Å. In the second Pt site, Pt(2) is bonded in a rectangular see-saw-like geometry to one Ru(2), one Pt(3), and two equivalent Pt(1) atoms. The Pt(2)-Pt(3) bond length is 2.62 Å. In the third Pt site, Pt(3) is bonded in a 3-coordinate geometry to three equivalent Pt(2) atoms. In the fourth Pt site, Pt(4) is bonded in a distorted rectangular see-saw-like geometry to one Ru(1) and three equivalent Pt(1) atoms.
