The material described by EuCu4P3 crystallizes in the tetragonal P4/mmm space group. Eu(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent P(2) atoms. Cu(1) is bonded to two equivalent Eu(1), two equivalent P(1), and two equivalent P(2) atoms to form a mixture of distorted edge, face, and corner-sharing CuEu2P4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded in a body-centered cubic geometry to eight equivalent Cu(1) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to four equivalent Eu(1), four equivalent Cu(1), and one P(2) atom. is represented by the CIF card [CIF]
