Y Re Ir Pb
YReIrPb crystallizes in the trigonal R3m space group. Y(1) is bonded in a distorted single-bond geometry to one Re(1), three equivalent Ir(1), and four equivalent Pb(1) atoms. The Y(1)-Re(1) bond length is 1.86 Å. All Y(1)-Ir(1) bond lengths are 3.07 Å. There are three shorter (2.87 Å) and one longer (3.35 Å) Y(1)-Pb(1) bond length. Re(1) is bonded in a single-bond geometry to one Y(1), four equivalent Ir(1), and three equivalent Pb(1) atoms. There are three shorter (2.87 Å) and one longer (3.35 Å) Re(1)-Ir(1) bond length. All Re(1)-Pb(1) bond lengths are 3.07 Å. Ir(1) is bonded in a 11-coordinate geometry to three equivalent Y(1), four equivalent Re(1), and four equivalent Pb(1) atoms. There are three shorter (2.87 Å) and one longer (3.35 Å) Ir(1)-Pb(1) bond length. Pb(1) is bonded in a 11-coordinate geometry to four equivalent Y(1), three equivalent Re(1), and four equivalent Ir(1) atoms.
