Ca Tc Os Os
CaTc(Os)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one os cl5 molecule and one CaTc cluster. In the CaTc cluster, Ca(1) is bonded in a single-bond geometry to one Tc(1) atom. The Ca(1)-Tc(1) bond length is 0.27 Å. Tc(1) is bonded in a single-bond geometry to one Ca(1) atom.
