Sr Sr Re Tc
Sr2ReTc crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2ReTc clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Re(1) atom. The Sr(1)-Re(1) bond length is 1.41 Å. In the second Sr site, Sr(2) is bonded in a water-like geometry to one Re(1) and one Tc(1) atom. The Sr(2)-Re(1) bond length is 1.41 Å. The Sr(2)-Tc(1) bond length is 1.20 Å. Re(1) is bonded in a water-like geometry to one Sr(1) and one Sr(2) atom. Tc(1) is bonded in a single-bond geometry to one Sr(2) atom.
