CrReAu2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrReAu2 clusters. Cr(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) atoms. Both Cr(1)-Au(1) bond lengths are 1.06 Å. Re(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) atoms. Both Re(1)-Au(1) bond lengths are 0.46 Å. Au(1) is bonded in a 3-coordinate geometry to one Cr(1), one Re(1), and one Au(1) atom. The Au(1)-Au(1) bond length is 0.51 Å.
