BeMn2Ag crystallizes in the triclinic P1 space group. Be(1) is bonded in a distorted bent 120 degrees geometry to one Mn(1), one Mn(2), and one Ag(1) atom. The Be(1)-Mn(1) bond length is 1.78 Å. The Be(1)-Mn(2) bond length is 0.65 Å. The Be(1)-Ag(1) bond length is 0.57 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 8-coordinate geometry to one Be(1), two equivalent Mn(1), two equivalent Mn(2), and three equivalent Ag(1) atoms. Both Mn(1)-Mn(1) bond lengths are 2.91 Å. There is one shorter (1.76 Å) and one longer (2.69 Å) Mn(1)-Mn(2) bond length. There are a spread of Mn(1)-Ag(1) bond distances ranging from 2.01-2.80 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Be(1) and two equivalent Mn(1) atoms. Ag(1) is bonded in a single-bond geometry to one Be(1) and three equivalent Mn(1) atoms.
