KNa2Re is Cyanogen Chloride-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three KNa2Re clusters. K(1) is bonded in a linear geometry to one Na(2) and one Re(1) atom. The K(1)-Na(2) bond length is 0.38 Å. The K(1)-Re(1) bond length is 0.38 Å. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a single-bond geometry to one Re(1) atom. The Na(1)-Re(1) bond length is 0.38 Å. In the second Na site, Na(2) is bonded in a single-bond geometry to one K(1) atom. Re(1) is bonded in a linear geometry to one K(1) and one Na(1) atom.
