Tc Ru Ru Ru Ru Pt
TcRu4Pt crystallizes in the trigonal R3m space group. Tc(1) is bonded in a 10-coordinate geometry to three equivalent Ru(1), three equivalent Ru(2), and four equivalent Pt(1) atoms. All Tc(1)-Ru(1) bond lengths are 2.42 Å. All Tc(1)-Ru(2) bond lengths are 3.22 Å. There is one shorter (2.72 Å) and three longer (3.22 Å) Tc(1)-Pt(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to one Tc(1), one Ru(2), two equivalent Ru(1), and two equivalent Pt(1) atoms. The Ru(1)-Ru(2) bond length is 1.95 Å. Both Ru(1)-Ru(1) bond lengths are 1.13 Å. There is one shorter (2.35 Å) and one longer (2.92 Å) Ru(1)-Pt(1) bond length. In the second Ru site, Ru(2) is bonded in a 9-coordinate geometry to three equivalent Tc(1), three equivalent Ru(1), and three equivalent Pt(1) atoms. All Ru(2)-Pt(1) bond lengths are 2.91 Å. Pt(1) is bonded in a 13-coordinate geometry to four equivalent Tc(1), three equivalent Ru(2), and six equivalent Ru(1) atoms.
