Sr Sr Be Cl
Sr2BeCl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2BeCl clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Cl(1) atom. The Sr(1)-Cl(1) bond length is 2.08 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Be(1) atom. The Sr(2)-Be(1) bond length is 1.47 Å. Be(1) is bonded in a distorted bent 150 degrees geometry to one Sr(2) and one Cl(1) atom. The Be(1)-Cl(1) bond length is 0.68 Å. Cl(1) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Be(1) atom.
