Title: Materials Data on PuMnAl by Materials Project

Abstract

PuMnAl is Frank-Kasper $$\mu$$ Phase-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are seven inequivalent Pu sites. In the first Pu site, Pu is bonded in a 12-coordinate geometry to four Pu, five Mn, and seven Al atoms. There are a spread of Pu–Pu bond distances ranging from 3.28–3.44 Å. There are a spread of Pu–Mn bond distances ranging from 2.99–3.23 Å. There are three shorter (3.16 Å) and four longer (3.19 Å) Pu–Al bond lengths. In the second Pu site, Pu is bonded in a 9-coordinate geometry to four Pu, seven Mn, and five Al atoms. There are one shorter (2.89 Å) and two longer (3.34 Å) Pu–Pu bond lengths. There are a spread of Pu–Mn bond distances ranging from 3.03–3.24 Å. There are one shorter (3.11 Å) and four longer (3.23 Å) Pu–Al bond lengths. In the third Pu site, Pu is bonded in a 9-coordinate geometry to four Pu, seven Mn, and five Al atoms. There are one shorter (3.28 Å) and two longer (3.34 Å) Pu–Pu bond lengths. There are a spread of Pu–Mn bond distances ranging from 3.03–3.24 Å. There are one shorter (3.11 Å) and four longer (3.23 Å) Pu–Al bond lengths. In the fourth Pu site, Pu is bonded in a 12-coordinate geometry to four Pu, five Mn, and seven Al atoms. Both Pu–Pu bond lengths are 3.34 Å. There are a spread of Pu–Mn bond distances ranging from 2.99–3.23 Å. There are three shorter (3.16 Å) and four longer (3.19 Å) Pu–Al bond lengths.

There are a spread of Mn–Mn bond distances ranging from 2.67–2.77 Å. Both Mn–Al bond lengths are 2.62 Å. In the third Mn site, Mn is bonded to six Pu, four equivalent Mn, and two equivalent Al atoms to form MnPu6Mn4Al2 cuboctahedra that share corners with six MnPu6Al6 cuboctahedra, corners with twelve AlPu6Mn4Al2 cuboctahedra, edges with six MnPu6Al6 cuboctahedra, faces with eight equivalent MnPu6Mn4Al2 cuboctahedra, and faces with ten AlPu6Mn4Al2 cuboctahedra. Both Mn–Al bond lengths are 2.61 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to six Pu, four Mn, and two equivalent Al atoms to form AlPu6Mn4Al2 cuboctahedra that share corners with four equivalent AlPu6Mn2Al4 cuboctahedra, corners with eight MnPu6Al6 cuboctahedra, edges with six equivalent AlPu6Mn4Al2 cuboctahedra, faces with eight AlPu6Mn4Al2 cuboctahedra, and faces with twelve MnPu6Al6 cuboctahedra. Both Al–Al bond lengths are 2.74 Å. In the second Al site, Al is bonded to six Pu, two equivalent Mn, and four Al atoms to form AlPu6Mn2Al4 cuboctahedra that share corners with eight AlPu6Mn4Al2 cuboctahedra, corners with ten MnPu6Mn4Al2 cuboctahedra, edges with two equivalent AlPu6Mn2Al4 cuboctahedra, edges with four equivalent MnPu6Mn4Al2 cuboctahedra, faces with eight MnPu6Al6 cuboctahedra, and faces with ten AlPu6Mn4Al2 cuboctahedra. There are one shorter (2.67 Å) and one longer (2.81 Å) Al–Al bond lengths.
