The compound described by Eu3(PdAs)4 crystallizes in the orthorhombic Pmmm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 14-coordinate geometry to two equivalent Pd(2), two equivalent Pd(3), four equivalent Pd(1), two equivalent As(2), and four equivalent As(1) atoms. In the second Eu site, Eu(2) is bonded to four equivalent Pd(1) and eight equivalent As(2) atoms to form a mixture of edge and face-sharing EuAs8Pd4 cuboctahedra. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), one As(1), and two equivalent As(2) atoms. In the second Pd site, Pd(2) is bonded to four equivalent Eu(1), four equivalent Pd(3), and four equivalent As(1) atoms to form a mixture of distorted corner and face-sharing PdEu4As4Pd4 cuboctahedra. In the third Pd site, Pd(3) is bonded to four equivalent Eu(1), four equivalent Pd(2), and four equivalent As(1) atoms to form a mixture of distorted corner and face-sharing PdEu4As4Pd4 cuboctahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Pd(1), two equivalent Pd(2), and two equivalent Pd(3) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), two equivalent Pd(1), and one As(2) atom. is represented by the CIF file [CIF]
