Ba Sr Sr Re
BaSr2Re crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaSr2Re clusters. Ba(1) is bonded in a single-bond geometry to one Re(1) atom. The Ba(1)-Re(1) bond length is 1.37 Å. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted single-bond geometry to one Sr(2) and one Re(1) atom. The Sr(1)-Sr(2) bond length is 2.06 Å. The Sr(1)-Re(1) bond length is 2.30 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Sr(1) atom. Re(1) is bonded in a 2-coordinate geometry to one Ba(1) and one Sr(1) atom.
