PrMn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1), three equivalent Mn(1), and nine equivalent Mn(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent Pr(1) and six equivalent Mn(2) atoms to form a mixture of edge, corner, and face-sharing MnPr6Mn6 cuboctahedra. In the second Mn site, Mn(2) is bonded to six equivalent Pr(1), two equivalent Mn(1), and four equivalent Mn(2) atoms to form a mixture of edge, corner, and face-sharing MnPr6Mn6 cuboctahedra.
PrMn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1), three equivalent Mn(1), and nine equivalent Mn(2) atoms. There is one shorter (3.24 Å) and three longer (3.35 Å) Pr(1)-Pr(1) bond lengths. All Pr(1)-Mn(1) bond lengths are 3.24 Å. There are three shorter (3.07 Å) and six longer (3.22 Å) Pr(1)-Mn(2) bond lengths. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent Pr(1) and six equivalent Mn(2) atoms to form a mixture of edge, corner, and face-sharing MnPr6Mn6 cuboctahedra. All Mn(1)-Mn(2) bond lengths are 2.61 Å. In the second Mn site, Mn(2) is bonded to six equivalent Pr(1), two equivalent Mn(1), and four equivalent Mn(2) atoms to form a mixture of edge, corner, and face-sharing MnPr6Mn6 cuboctahedra. There are two shorter (2.68 Å) and two longer (2.87 Å) Mn(2)-Mn(2) bond lengths.
