LiCu2P2 crystallizes in the tetragonal I4/mmm space group. Li(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent P(1) atoms. Cu(1) is bonded to four equivalent Li(1) and four equivalent P(1) atoms to form a mixture of distorted corner, face, and edge-sharing CuLi4P4 tetrahedra. P(1) is bonded in a 9-coordinate geometry to four equivalent Li(1), four equivalent Cu(1), and one P(1) atom.
