MnNCN crystallizes in the trigonal R-3m space group. Mn(1) is bonded to six equivalent N(1) atoms to form edge-sharing MnN6 octahedra. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to three equivalent Mn(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing NMn3C trigonal pyramids.
MnNCN crystallizes in the trigonal R-3m space group. Mn(1) is bonded to six equivalent N(1) atoms to form edge-sharing MnN6 octahedra. All Mn(1)-N(1) bond lengths are 2.26 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 Mn(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing NMn3C trigonal pyramids.
