Ir Ir Ru Pb
RuIr2Pb crystallizes in the monoclinic Cm space group. Ru(1) is bonded in a 4-coordinate geometry to eight equivalent Ir(1) atoms. There are a spread of Ru(1)-Ir(1) bond distances ranging from 2.34-3.28 Å. Ir(1) is bonded in a 11-coordinate geometry to four equivalent Ru(1), three equivalent Ir(1), and four equivalent Pb(1) atoms. There is one shorter (2.76 Å) and two longer (2.89 Å) Ir(1)-Ir(1) bond lengths. There are a spread of Ir(1)-Pb(1) bond distances ranging from 2.34-3.28 Å. Pb(1) is bonded in a 4-coordinate geometry to eight equivalent Ir(1) atoms.
