Be Be B Cl
Be2BCl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2BCl cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Cl(1) atom. The Be(1)-Cl(1) bond length is 1.18 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one B(1) and one Cl(1) atom. The Be(2)-B(1) bond length is 2.14 Å. The Be(2)-Cl(1) bond length is 1.18 Å. B(1) is bonded in a single-bond geometry to one Be(2) atom. Cl(1) is bonded in a linear geometry to one Be(1) and one Be(2) atom.
