Sr Re Re Si
SrReReSi is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReSi clusters and two SrRe clusters. In each ReSi cluster, Re(1) is bonded in a distorted single-bond geometry to one Si(1) atom. The Re(1)-Si(1) bond length is 0.55 Å. Si(1) is bonded in a single-bond geometry to one Re(1) atom. In each SrRe cluster, Sr(1) is bonded in a single-bond geometry to one Re(2) atom. The Sr(1)-Re(2) bond length is 1.15 Å. Re(2) is bonded in a single-bond geometry to one Sr(1) atom.
