Co2C is Hydrophilite structured and crystallizes in the orthorhombic Pnnm space group. Co(1) is bonded in a distorted trigonal planar geometry to three equivalent C(1) atoms. C(1) is bonded to six equivalent Co(1) atoms to form a mixture of edge and corner-sharing CCo6 octahedra. The corner-sharing octahedral tilt angles are 52°.
Co2C is Hydrophilite structured and crystallizes in the orthorhombic Pnnm space group. Co(1) is bonded in a distorted trigonal planar geometry to three equivalent C(1) atoms. All Co(1)-C(1) bond lengths are 1.90 Å. C(1) is bonded to six equivalent Co(1) atoms to form a mixture of edge and corner-sharing CCo6 octahedra. The corner-sharing octahedral tilt angles are 52°.
