Sr Sr Ca Co
Sr2CaCo crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2CaCo clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Co(1) atom. The Sr(1)-Co(1) bond length is 2.65 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Ca(1) atom. The Sr(2)-Ca(1) bond length is 2.52 Å. Ca(1) is bonded in a single-bond geometry to one Sr(2) and one Co(1) atom. The Ca(1)-Co(1) bond length is 0.13 Å. Co(1) is bonded in a single-bond geometry to one Sr(1) and one Ca(1) atom.
