SrCaTcCu is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three SrCaTcCu clusters. Sr(1) is bonded in a linear geometry to one Tc(1) and one Cu(1) atom. The Sr(1)-Tc(1) bond length is 2.14 Å. The Sr(1)-Cu(1) bond length is 2.14 Å. Ca(1) is bonded in a single-bond geometry to one Tc(1) atom. The Ca(1)-Tc(1) bond length is 2.14 Å. Tc(1) is bonded in a linear geometry to one Sr(1) and one Ca(1) atom. Cu(1) is bonded in a single-bond geometry to one Sr(1) atom.
