Ba Ba La Tc
Ba2LaTc crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2LaTc clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Tc(1) atom. The Ba(1)-Tc(1) bond length is 1.01 Å. In the second Ba site, Ba(2) is bonded in a distorted single-bond geometry to one La(1) atom. The Ba(2)-La(1) bond length is 3.05 Å. La(1) is bonded in a distorted single-bond geometry to one Ba(2) and one Tc(1) atom. The La(1)-Tc(1) bond length is 2.29 Å. Tc(1) is bonded in a distorted single-bond geometry to one Ba(1) and one La(1) atom.
