(Co)2TcBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cobalt molecules and two TcBi clusters. In each TcBi cluster, Tc(1) is bonded in a single-bond geometry to one Bi(1) atom. The Tc(1)-Bi(1) bond length is 0.35 Å. Bi(1) is bonded in a single-bond geometry to one Tc(1) atom.
