The structure described by EuCu4Pd crystallizes in the hexagonal P-6m2 space group. Eu(1) is bonded in a 18-coordinate geometry to three equivalent Pd(1), three equivalent Cu(1), and twelve equivalent Cu(2) atoms. Pd(1) is bonded to three equivalent Eu(1), three equivalent Cu(1), and six equivalent Cu(2) atoms to form distorted PdEu3Cu9 cuboctahedra that share corners with nine equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, corners with twelve equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra, edges with six equivalent Pd(1)Eu3Cu9 cuboctahedra, faces with two equivalent Pd(1)Eu3Cu9 cuboctahedra, faces with three equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, and faces with eighteen equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to three equivalent Eu(1), three equivalent Pd(1), and six equivalent Cu(2) atoms to form CuEu3Cu6Pd3 cuboctahedra that share corners with nine equivalent Pd(1)Eu3Cu9 cuboctahedra, corners with twelve equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra, edges with six equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, faces with two equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, faces with three equivalent Pd(1)Eu3Cu9 cuboctahedra, and faces with eighteen equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra. In the second Cu site, Cu(2) is bonded to four equivalent Eu(1), two equivalent Pd(1), two equivalent Cu(1), and four equivalent Cu(2) atoms to form distorted CuEu4Cu6Pd2 cuboctahedra that share corners with four equivalent Pd(1)Eu3Cu9 cuboctahedra, corners with four equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, corners with sixteen equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra, edges with ten equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra, faces with six equivalent Pd(1)Eu3Cu9 cuboctahedra, faces with six equivalent Cu(1)Eu3Cu6Pd3 cuboctahedra, and faces with ten equivalent Cu(2)Eu4Cu6Pd2 cuboctahedra. is represented by the CIF card [CIF]
