Ca2CoN2 crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded to five equivalent N(1) atoms to form a mixture of corner and edge-sharing CaN5 square pyramids. Co(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to five equivalent Ca(1) and one Co(1) atom to form a mixture of corner and edge-sharing NCa5Co octahedra. The corner-sharing octahedral tilt angles range from 0-6°.
Ca2CoN2 crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded to five equivalent N(1) atoms to form a mixture of corner and edge-sharing CaN5 square pyramids. There is one shorter (2.47 Å) and four longer (2.52 Å) Ca(1)-N(1) bond lengths. Co(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Co(1)-N(1) bond lengths are 1.78 Å. N(1) is bonded to five equivalent Ca(1) and one Co(1) atom to form a mixture of corner and edge-sharing NCa5Co octahedra. The corner-sharing octahedral tilt angles range from 0-6°.
