Sr Sr Be Tc
Sr2BeTc crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2BeTc clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 1-coordinate geometry to one Sr(2) atom. The Sr(1)-Sr(2) bond length is 0.73 Å. In the second Sr site, Sr(2) is bonded in a 2-coordinate geometry to one Sr(1) and one Tc(1) atom. The Sr(2)-Tc(1) bond length is 1.12 Å. Be(1) is bonded in a single-bond geometry to one Tc(1) atom. The Be(1)-Tc(1) bond length is 0.24 Å. Tc(1) is bonded in a single-bond geometry to one Sr(2) and one Be(1) atom.
