Be Be Cd Br
CdBeBeBr crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeBr cluster and one CdBe cluster. In the BeBr cluster, Be(2) is bonded in a single-bond geometry to one Br(1) atom. The Be(2)-Br(1) bond length is 0.38 Å. Br(1) is bonded in a single-bond geometry to one Be(2) atom. In the CdBe cluster, Be(1) is bonded in a single-bond geometry to one Cd(1) atom. The Be(1)-Cd(1) bond length is 0.38 Å. Cd(1) is bonded in a distorted single-bond geometry to one Be(1) atom.
