Be Be Re Ag
Be2ReAg crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2ReAg cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Re(1) atom. The Be(1)-Re(1) bond length is 1.64 Å. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Re(1) atom. The Be(2)-Re(1) bond length is 1.85 Å. Re(1) is bonded in a distorted single-bond geometry to one Be(1), one Be(2), and one Ag(1) atom. The Re(1)-Ag(1) bond length is 0.09 Å. Ag(1) is bonded in a single-bond geometry to one Re(1) atom.
