The material structure described by Eu4Pd12B crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to four equivalent Pd(1), four equivalent Pd(2), and four equivalent Pd(4) atoms to form EuPd12 cuboctahedra that share corners with four equivalent Eu(2)Pd12 cuboctahedra, corners with eight equivalent Eu(1)Pd12 cuboctahedra, edges with four equivalent Pd(5)Eu4Pd8 cuboctahedra,  a faceface with one Eu(2)Pd12 cuboctahedra, faces with five equivalent Eu(1)Pd12 cuboctahedra, and faces with four equivalent B(1)Pd6 octahedra. In the second Eu site, Eu(2) is bonded to four equivalent Pd(2), four equivalent Pd(3), and four equivalent Pd(5) atoms to form EuPd12 cuboctahedra that share corners with four equivalent Eu(1)Pd12 cuboctahedra, corners with eight equivalent Eu(2)Pd12 cuboctahedra, edges with four equivalent Pd(5)Eu4Pd8 cuboctahedra,  a faceface with one Eu(1)Pd12 cuboctahedra, faces with four equivalent Pd(5)Eu4Pd8 cuboctahedra, and faces with five equivalent Eu(2)Pd12 cuboctahedra. There are five inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Eu(1) and two equivalent B(1) atoms to form a mixture of distorted edge, face, and corner-sharing PdEu4B2 octahedra. The corner-sharing octahedra are not tilted. In the second Pd site, Pd(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Eu(1), two equivalent Eu(2), and two equivalent Pd(5) atoms. In the third Pd site, Pd(3) is bonded in a distorted square co-planar geometry to four equivalent Eu(2) and four equivalent Pd(5) atoms. In the fourth Pd site, Pd(4) is bonded in a 1-coordinate geometry to four equivalent Eu(1) and one B(1) atom. In the fifth Pd site, Pd(5) is bonded to four equivalent Eu(2), four equivalent Pd(2), and four equivalent Pd(3) atoms to form distorted PdEu4Pd8 cuboctahedra that share corners with eight equivalent Pd(5)Eu4Pd8 cuboctahedra, edges with four equivalent Eu(1)Pd12 cuboctahedra, edges with four equivalent Eu(2)Pd12 cuboctahedra, faces with four equivalent Eu(2)Pd12 cuboctahedra, and faces with five equivalent Pd(5)Eu4Pd8 cuboctahedra. B(1) is bonded to two equivalent Pd(4) and four equivalent Pd(1) atoms to form BPd6 octahedra that share corners with four equivalent B(1)Pd6 octahedra and faces with eight equivalent Eu(1)Pd12 cuboctahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
