Be Co Co Br
BeCoCoBr crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeCo cluster and one CoBr cluster. In the BeCo cluster, Be(1) is bonded in a single-bond geometry to one Co(2) atom. The Be(1)-Co(2) bond length is 0.71 Å. Co(2) is bonded in a single-bond geometry to one Be(1) atom. In the CoBr cluster, Co(1) is bonded in a single-bond geometry to one Br(1) atom. The Co(1)-Br(1) bond length is 0.71 Å. Br(1) is bonded in a single-bond geometry to one Co(1) atom.
