Y6Mn23 crystallizes in the cubic Fm-3m space group. Y(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 in a 13-coordinate geometry to three equivalent Y(1), one Mn(1), three equivalent Mn(2), three equivalent Mn(3), and three equivalent Mn(4) atoms. In the second Mn site, Mn(1) is bonded in a body-centered cubic geometry to eight equivalent Mn(4) atoms. In the third Mn site, Mn(2) is bonded to four equivalent Y(1), four equivalent Mn(3), and four equivalent Mn(4) atoms to form a mixture of face and corner-sharing MnY4Mn8 cuboctahedra. In the fourth Mn site, Mn(3) is bonded in a distorted q6 geometry to three equivalent Y(1), three equivalent Mn(2), three equivalent Mn(3), and three equivalent Mn(4) atoms.
