Sr Zr Cl Cl
(SrZrCl)2Cl2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two hydrochloric acid atoms and two SrZrCl clusters. In each SrZrCl cluster, Sr(1) is bonded in a single-bond geometry to one Zr(1) and one Cl(1) atom. The Sr(1)-Zr(1) bond length is 1.46 Å. The Sr(1)-Cl(1) bond length is 0.65 Å. Zr(1) is bonded in a single-bond geometry to one Sr(1) atom. Cl(1) is bonded in a single-bond geometry to one Sr(1) atom.
