ReN is Tungsten Carbide structured and crystallizes in the triclinic P1 space group. Re(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. There are a spread of Re(1)-N(1) bond distances ranging from 2.08-2.48 Å. N(1) is bonded in a 6-coordinate geometry to six equivalent Re(1) atoms.
