Sr Sr Be Re
SrBeSrRe is beta oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrBe clusters and two SrRe clusters. In each SrBe cluster, Sr(1) is bonded in a distorted single-bond geometry to one Be(1) atom. The Sr(1)-Be(1) bond length is 1.91 Å. Be(1) is bonded in a single-bond geometry to one Sr(1) atom. In each SrRe cluster, Sr(2) is bonded in a single-bond geometry to one Re(1) atom. The Sr(2)-Re(1) bond length is 0.83 Å. Re(1) is bonded in a single-bond geometry to one Sr(2) atom.
