Mn3Pd5 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a body-centered cubic geometry to four equivalent Pd(2) and four equivalent Pd(3) atoms. In the second Mn site, Mn(2) is bonded in a 10-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), and four equivalent Pd(3) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Mn(2) atoms to form distorted edge-sharing PdMn4 cuboctahedra. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms. In the third Pd site, Pd(3) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms.
Mn3Pd5 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a body-centered cubic geometry to four equivalent Pd(2) and four equivalent Pd(3) atoms. All Mn(1)-Pd(2) bond lengths are 2.72 Å. All Mn(1)-Pd(3) bond lengths are 2.60 Å. In the second Mn site, Mn(2) is bonded in a 10-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), and four equivalent Pd(3) atoms. Both Mn(2)-Pd(1) bond lengths are 2.75 Å. All Mn(2)-Pd(2) bond lengths are 2.73 Å. There are two shorter (2.70 Å) and two longer (2.76 Å) Mn(2)-Pd(3) bond lengths. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Mn(2) atoms to form distorted edge-sharing PdMn4 cuboctahedra. In the second Pd site, Pd(2) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms. In the third Pd site, Pd(3) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms.
