Mn Be Be Ag
Be2MnAg crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted single-bond geometry to one Be(2), one Mn(1), and two equivalent Ag(1) atoms. The Be(1)-Be(2) bond length is 0.67 Å. The Be(1)-Mn(1) bond length is 1.72 Å. There is one shorter (2.43 Å) and one longer (2.53 Å) Be(1)-Ag(1) bond length. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Be(1), one Mn(1), and two equivalent Ag(1) atoms. The Be(2)-Mn(1) bond length is 1.68 Å. There is one shorter (2.43 Å) and one longer (2.53 Å) Be(2)-Ag(1) bond length. Mn(1) is bonded in a distorted bent 150 degrees geometry to one Be(1), one Be(2), and one Ag(1) atom. The Mn(1)-Ag(1) bond length is 2.70 Å. Ag(1) is bonded in a 7-coordinate geometry to two equivalent Be(1), two equivalent Be(2), one Mn(1), and two equivalent Ag(1) atoms. Both Ag(1)-Ag(1) bond lengths are 2.52 Å.
