SrReCoRe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CoRe clusters and two SrRe clusters. In each CoRe cluster, Re(2) is bonded in a single-bond geometry to one Co(1) atom. The Re(2)-Co(1) bond length is 0.95 Å. Co(1) is bonded in a single-bond geometry to one Re(2) atom. In each SrRe cluster, Sr(1) is bonded in a distorted single-bond geometry to one Re(1) atom. The Sr(1)-Re(1) bond length is 2.25 Å. Re(1) is bonded in a single-bond geometry to one Sr(1) atom.
