Mn3Pd5Sn2 is Heusler-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are four inequivalent Mn sites. In the first Mn site, Mn is bonded in a body-centered cubic geometry to eight Pd atoms. There are a spread of Mn–Pd bond distances ranging from 2.77–2.81 Å. In the second Mn site, Mn is bonded in a body-centered cubic geometry to eight Pd atoms. There are six shorter (2.77 Å) and two longer (2.78 Å) Mn–Pd bond lengths. In the third Mn site, Mn is bonded in a body-centered cubic geometry to eight Pd atoms. There are a spread of Mn–Pd bond distances ranging from 2.71–2.81 Å. In the fourth Mn site, Mn is bonded in a body-centered cubic geometry to eight Pd atoms. There are two shorter (2.75 Å) and six longer (2.76 Å) Mn–Pd bond lengths. There are six inequivalent Pd sites. In the first Pd site, Pd is bonded in a body-centered cubic geometry to four Mn and four equivalent Sn atoms. All Pd–Sn bond lengths are 2.77 Å. In the second Pd site, Pd is bonded in a body-centered cubic geometry to seven Mn and one Sn atom. The Pd–Sn bond length is 2.80 Å. In the third Pd site, Pd is bonded in a body-centered cubic geometry to five Mn and three equivalent Sn atoms. All Pd–Sn bond lengths are 2.78 Å.
