The compound described by Li2CN2 crystallizes in the tetragonal I4/mmm space group. Li(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing LiN4 tetrahedra. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and one C(1) atom. is represented by the CIF file [CIF]
