Co2N is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. Co(1) is bonded in a distorted trigonal planar geometry to three equivalent N(1) atoms. N(1) is bonded to six equivalent Co(1) atoms to form a mixture of corner and edge-sharing NCo6 octahedra. The corner-sharing octahedral tilt angles are 50°.
Co2N is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. Co(1) is bonded in a distorted trigonal planar geometry to three equivalent N(1) atoms. There is one shorter (1.86 Å) and two longer (1.88 Å) Co(1)-N(1) bond lengths. N(1) is bonded to six equivalent Co(1) atoms to form a mixture of corner and edge-sharing NCo6 octahedra. The corner-sharing octahedral tilt angles are 50°.
