CrNCN crystallizes in the hexagonal P6_3/mmc space group. Cr(1) is bonded to six equivalent N(1) atoms to form edge-sharing CrN6 octahedra. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to three equivalent Cr(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing NCr3C trigonal pyramids.
CrNCN crystallizes in the hexagonal P6_3/mmc space group. Cr(1) is bonded to six equivalent N(1) atoms to form edge-sharing CrN6 octahedra. All Cr(1)-N(1) bond lengths are 2.19 Å. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both C(1)-N(1) bond lengths are 1.24 Å. N(1) is bonded to three equivalent Cr(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing NCr3C trigonal pyramids.
