The structure described by LiCa2CuN2 crystallizes in the tetragonal P4_2/mnm space group. Li(1) is bonded in a linear geometry to two equivalent N(1) atoms. Ca(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing CaN4 tetrahedra. Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to one Li(1), four equivalent Ca(1), and one Cu(1) atom to form a mixture of corner and edge-sharing NLiCa4Cu octahedra. The corner-sharing octahedral tilt angles range from 0-64°. is represented by the CIF card [CIF]
