NaBC crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to six equivalent B(1) and six equivalent C(1) atoms to form a mixture of distorted face and edge-sharing NaB6C6 cuboctahedra. B(1) is bonded in a trigonal planar geometry to six equivalent Na(1) and three equivalent C(1) atoms. C(1) is bonded in a trigonal planar geometry to six equivalent Na(1) and three equivalent B(1) atoms.
