NaCrAu2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaCrAu2 clusters. Na(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) atoms. Both Na(1)-Au(1) bond lengths are 2.40 Å. Cr(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) atoms. Both Cr(1)-Au(1) bond lengths are 2.40 Å. Au(1) is bonded in a 2-coordinate geometry to one Na(1) and one Cr(1) atom.
