The structure described by Ce2Mn3PdSi4 crystallizes in the tetragonal P-4m2 space group. Ce(1) is bonded in a 16-coordinate geometry to two equivalent Mn(1), two equivalent Mn(2), two equivalent Mn(3), two equivalent Pd(1), four equivalent Si(1), and four equivalent Si(2) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent Ce(1) and four equivalent Si(2) atoms to form distorted MnCe4Si4 tetrahedra that share corners with eight equivalent Pd(1)Ce4Mn4Si4 cuboctahedra, edges with four equivalent Mn(1)Ce4Si4 tetrahedra, and faces with four equivalent Mn(3)Ce4Si4 tetrahedra. In the second Mn site, Mn(2) is bonded in a 12-coordinate geometry to four equivalent Ce(1), four equivalent Pd(1), and four equivalent Si(1) atoms. In the third Mn site, Mn(3) is bonded to four equivalent Ce(1) and four equivalent Si(2) atoms to form distorted MnCe4Si4 tetrahedra that share corners with four equivalent Pd(1)Ce4Mn4Si4 cuboctahedra, edges with two equivalent Pd(1)Ce4Mn4Si4 cuboctahedra, edges with four equivalent Mn(3)Ce4Si4 tetrahedra, and faces with four equivalent Mn(1)Ce4Si4 tetrahedra. Pd(1) is bonded to four equivalent Ce(1), four equivalent Mn(2), and four equivalent Si(1) atoms to form distorted PdCe4Mn4Si4 cuboctahedra that share corners with four equivalent Pd(1)Ce4Mn4Si4 cuboctahedra, corners with four equivalent Mn(3)Ce4Si4 tetrahedra, corners with eight equivalent Mn(1)Ce4Si4 tetrahedra, edges with two equivalent Mn(3)Ce4Si4 tetrahedra, and faces with four equivalent Pd(1)Ce4Mn4Si4 cuboctahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Mn(2), two equivalent Pd(1), and one Si(2) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Mn(1), two equivalent Mn(3), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
