Ru3Pt crystallizes in the triclinic P1 space group. There are three inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to one Ru(2), two equivalent Ru(3), and one Pt(1) atom. The Ru(1)-Ru(2) bond length is 2.16 Å. There is one shorter (2.06 Å) and one longer (2.80 Å) Ru(1)-Ru(3) bond length. The Ru(1)-Pt(1) bond length is 2.48 Å. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to one Ru(1), one Ru(3), and one Pt(1) atom. The Ru(2)-Ru(3) bond length is 2.37 Å. The Ru(2)-Pt(1) bond length is 1.59 Å. In the third Ru site, Ru(3) is bonded in a 7-coordinate geometry to one Ru(2), two equivalent Ru(1), two equivalent Ru(3), and two equivalent Pt(1) atoms. Both Ru(3)-Ru(3) bond lengths are 2.71 Å. There is one shorter (2.48 Å) and one longer (2.68 Å) Ru(3)-Pt(1) bond length. Pt(1) is bonded in a distorted single-bond geometry to one Ru(1), one Ru(2), and two equivalent Ru(3) atoms.
