MgReCu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgReCu cluster. Mg(1) is bonded in a 2-coordinate geometry to one Re(1) and one Cu(1) atom. The Mg(1)-Re(1) bond length is 1.24 Å. The Mg(1)-Cu(1) bond length is 2.00 Å. Re(1) is bonded in a single-bond geometry to one Mg(1) atom. Cu(1) is bonded in a distorted single-bond geometry to one Mg(1) atom.
