Y Y Y Y Be Pd
BeY4Pd crystallizes in the trigonal R3m space group. Be(1) is bonded in a distorted tetrahedral geometry to three equivalent Y(1) and one Pd(1) atom. All Be(1)-Y(1) bond lengths are 3.08 Å. The Be(1)-Pd(1) bond length is 2.28 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 5-coordinate geometry to one Be(1), one Y(2), two equivalent Y(1), and one Pd(1) atom. The Y(1)-Y(2) bond length is 1.61 Å. Both Y(1)-Y(1) bond lengths are 0.93 Å. The Y(1)-Pd(1) bond length is 1.97 Å. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to three equivalent Y(1) and three equivalent Pd(1) atoms. All Y(2)-Pd(1) bond lengths are 3.85 Å. Pd(1) is bonded in a 4-coordinate geometry to one Be(1), three equivalent Y(1), and three equivalent Y(2) atoms.
