Be Ag Ag Cl
BeAg2Cl crystallizes in the triclinic P1 space group. Be(1) is bonded in a single-bond geometry to two equivalent Ag(1) and one Cl(1) atom. There is one shorter (2.54 Å) and one longer (2.88 Å) Be(1)-Ag(1) bond length. The Be(1)-Cl(1) bond length is 1.38 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent Be(1), one Ag(2), two equivalent Ag(1), and one Cl(1) atom. The Ag(1)-Ag(2) bond length is 2.60 Å. Both Ag(1)-Ag(1) bond lengths are 2.98 Å. The Ag(1)-Cl(1) bond length is 2.56 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Ag(1) and one Cl(1) atom. The Ag(2)-Cl(1) bond length is 1.24 Å. Cl(1) is bonded in a distorted bent 150 degrees geometry to one Be(1), one Ag(1), and one Ag(2) atom.
