Y Be Ag Ag
BeYAg2 crystallizes in the triclinic P1 space group. Be(1) is bonded in a 6-coordinate geometry to two equivalent Y(1), two equivalent Ag(1), and two equivalent Ag(2) atoms. There is one shorter (2.05 Å) and one longer (3.05 Å) Be(1)-Y(1) bond length. There is one shorter (1.88 Å) and one longer (2.96 Å) Be(1)-Ag(1) bond length. There is one shorter (2.05 Å) and one longer (3.05 Å) Be(1)-Ag(2) bond length. Y(1) is bonded in a single-bond geometry to two equivalent Be(1) and one Ag(1) atom. The Y(1)-Ag(1) bond length is 1.16 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to two equivalent Be(1), one Y(1), and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 1.16 Å. In the second Ag site, Ag(2) is bonded in a 1-coordinate geometry to two equivalent Be(1) and one Ag(1) atom.
