Sr Sr Zn Fe
SrFeZnSr crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrFe clusters and two ZnSr clusters. In each SrFe cluster, Sr(2) is bonded in a distorted single-bond geometry to one Fe(1) atom. The Sr(2)-Fe(1) bond length is 1.05 Å. Fe(1) is bonded in a single-bond geometry to one Sr(2) atom. In each ZnSr cluster, Sr(1) is bonded in a single-bond geometry to one Zn(1) atom. The Sr(1)-Zn(1) bond length is 0.73 Å. Zn(1) is bonded in a single-bond geometry to one Sr(1) atom.
