NaCuCuMn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one copper;sodium molecule and one CuMn cluster. In the CuMn cluster, Mn(1) is bonded in a single-bond geometry to one Cu(1) atom. The Mn(1)-Cu(1) bond length is 2.09 Å. Cu(1) is bonded in a 1-coordinate geometry to one Mn(1) atom.
