V5Mn7Al4 is Heusler-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are five inequivalent V sites. In the first V site, V is bonded in a distorted body-centered cubic geometry to three equivalent V and five Mn atoms. All V–V bond lengths are 2.54 Å. There are a spread of V–Mn bond distances ranging from 2.53–2.56 Å. In the second V site, V is bonded in a distorted body-centered cubic geometry to one V and seven Mn atoms. The V–V bond length is 2.53 Å. All V–Mn bond lengths are 2.53 Å. In the third V site, V is bonded in a body-centered cubic geometry to eight Mn atoms. There are one shorter (2.52 Å) and seven longer (2.53 Å) V–Mn bond lengths. In the fourth V site, V is bonded in a body-centered cubic geometry to eight Mn atoms. There are one shorter (2.51 Å) and seven longer (2.53 Å) V–Mn bond lengths. In the fifth V site, V is bonded in a distorted body-centered cubic geometry to four V, six Mn, and four Al atoms. There are three shorter (2.93 Å) and three longer (2.94 Å) V–Mn bond lengths. There are three shorter (2.53 Å) and one longer (2.56 Å) V–Al bond lengths. There are seven inequivalent Mn sites. In the first Mn site, Mn is bonded in a distorted body-centered cubic geometry to seven V and four Al atoms. There are three shorter (2.53 Å) and one longer (2.57 Å) Mn–Al bond lengths. In the second Mn site, Mn is bonded in a distorted body-centered cubic geometry to seven V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. In the third Mn site, Mn is bonded in a body-centered cubic geometry to four V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. In the fourth Mn site, Mn is bonded in a body-centered cubic geometry to four V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. In the fifth Mn site, Mn is bonded in a body-centered cubic geometry to four V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. In the sixth Mn site, Mn is bonded in a body-centered cubic geometry to four V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. In the seventh Mn site, Mn is bonded in a body-centered cubic geometry to four V and four Al atoms. There are one shorter (2.52 Å) and three longer (2.53 Å) Mn–Al bond lengths. There are four inequivalent Al sites. In the first Al site, Al is bonded in a body-centered cubic geometry to eight Mn atoms. In the second Al site, Al is bonded in a body-centered cubic geometry to eight Mn atoms. In the third Al site, Al is bonded in a distorted body-centered cubic geometry to one V and seven Mn atoms. In the fourth Al site, Al is bonded in a distorted body-centered cubic geometry to three equivalent V and five Mn atoms.
