The material described by EuPdMg crystallizes in the monoclinic Pm space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to one Pd(1), one Pd(2), and two equivalent Pd(4) atoms to form a mixture of distorted edge and corner-sharing MgPd4 tetrahedra. In the second Mg site, Mg(2) is bonded to one Pd(1), one Pd(2), and two equivalent Pd(3) atoms to form a mixture of distorted edge and corner-sharing MgPd4 tetrahedra. In the third Mg site, Mg(3) is bonded to one Pd(3), one Pd(4), and two equivalent Pd(2) atoms to form a mixture of distorted edge and corner-sharing MgPd4 tetrahedra. In the fourth Mg site, Mg(4) is bonded to one Pd(3), one Pd(4), and two equivalent Pd(1) atoms to form a mixture of distorted edge and corner-sharing MgPd4 tetrahedra. There are four inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 5-coordinate geometry to one Pd(1), two equivalent Pd(3), and two equivalent Pd(4) atoms. In the second Eu site, Eu(2) is bonded in a 5-coordinate geometry to one Pd(2), two equivalent Pd(3), and two equivalent Pd(4) atoms. In the third Eu site, Eu(3) is bonded in a 5-coordinate geometry to one Pd(3), two equivalent Pd(1), and two equivalent Pd(2) atoms. In the fourth Eu site, Eu(4) is bonded in a 5-coordinate geometry to one Pd(4), two equivalent Pd(1), and two equivalent Pd(2) atoms. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to one Mg(1), one Mg(2), two equivalent Mg(4), one Eu(1), two equivalent Eu(3), and two equivalent Eu(4) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to one Mg(1), one Mg(2), two equivalent Mg(3), one Eu(2), two equivalent Eu(3), and two equivalent Eu(4) atoms. In the third Pd site, Pd(3) is bonded in a 9-coordinate geometry to one Mg(3), one Mg(4), two equivalent Mg(2), one Eu(3), two equivalent Eu(1), and two equivalent Eu(2) atoms. In the fourth Pd site, Pd(4) is bonded in a 9-coordinate geometry to one Mg(3), one Mg(4), two equivalent Mg(1), one Eu(4), two equivalent Eu(1), and two equivalent Eu(2) atoms. is represented by the CIF card [CIF]
