The structure described by Pr6Mn23 crystallizes in the cubic Fm-3m space group. Pr(1) is bonded in a 12-coordinate geometry to four equivalent Mn(2), four equivalent Mn(3), and four equivalent Mn(4) atoms. There are four inequivalent Mn sites. In the first Mn site, Mn(4) is bonded to three equivalent Pr(1), three equivalent Mn(2), three equivalent Mn(3), and three equivalent Mn(4) atoms to form MnPr3Mn9 cuboctahedra that share corners with six equivalent Mn(4)Pr3Mn9 cuboctahedra, corners with six equivalent Mn(2)Pr4Mn8 cuboctahedra, faces with six equivalent Mn(4)Pr3Mn9 cuboctahedra, and faces with six equivalent Mn(2)Pr4Mn8 cuboctahedra. In the second Mn site, Mn(1) is bonded in a body-centered cubic geometry to eight equivalent Mn(3) atoms. In the third Mn site, Mn(2) is bonded to four equivalent Pr(1), four equivalent Mn(3), and four equivalent Mn(4) atoms to form MnPr4Mn8 cuboctahedra that share corners with four equivalent Mn(2)Pr4Mn8 cuboctahedra, corners with eight equivalent Mn(4)Pr3Mn9 cuboctahedra, faces with eight equivalent Mn(4)Pr3Mn9 cuboctahedra, and faces with eight equivalent Mn(2)Pr4Mn8 cuboctahedra. In the fourth Mn site, Mn(3) is bonded in a 13-coordinate geometry to three equivalent Pr(1), one Mn(1), three equivalent Mn(2), three equivalent Mn(3), and three equivalent Mn(4) atoms. is represented by the CIF file [CIF]
