Be Ag Ir Ir
BeIr2Ag is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeIr2Ag clusters. Be(1) is bonded in a 3-coordinate geometry to two equivalent Ir(1) and one Ag(1) atom. Both Be(1)-Ir(1) bond lengths are 0.48 Å. The Be(1)-Ag(1) bond length is 0.42 Å. Ir(1) is bonded in a 3-coordinate geometry to one Be(1), one Ir(1), and one Ag(1) atom. The Ir(1)-Ir(1) bond length is 0.42 Å. The Ir(1)-Ag(1) bond length is 0.48 Å. Ag(1) is bonded in a 3-coordinate geometry to one Be(1) and two equivalent Ir(1) atoms.
