K Ir Ru Pb
KRuIrPb crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to four equivalent Ru(1), six equivalent Ir(1), and one Pb(1) atom. There are three shorter (2.90 Å) and one longer (3.30 Å) K(1)-Ru(1) bond length. There are three shorter (3.12 Å) and three longer (3.85 Å) K(1)-Ir(1) bond lengths. The K(1)-Pb(1) bond length is 2.03 Å. Ru(1) is bonded in a 4-coordinate geometry to four equivalent K(1) and four equivalent Ir(1) atoms. There are three shorter (2.90 Å) and one longer (3.30 Å) Ru(1)-Ir(1) bond length. Ir(1) is bonded in a 14-coordinate geometry to six equivalent K(1), four equivalent Ru(1), and four equivalent Pb(1) atoms. There are three shorter (2.90 Å) and one longer (3.30 Å) Ir(1)-Pb(1) bond length. Pb(1) is bonded in a single-bond geometry to one K(1) and four equivalent Ir(1) atoms.
