EuCu3Pd2 crystallizes in the hexagonal P6/mmm space group. Eu(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(1) and twelve equivalent Cu(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent Cu(1) atoms. Cu(1) is bonded to four equivalent Eu(1), four equivalent Pd(1), and four equivalent Cu(1) atoms to form a mixture of distorted corner, face, and edge-sharing CuEu4Cu4Pd4 cuboctahedra.
