Mn is alpha structured and crystallizes in the cubic I-43m space group. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 16-coordinate geometry to four equivalent Mn(2) and twelve equivalent Mn(4) atoms. In the second Mn site, Mn(2) is bonded in a 16-coordinate geometry to one Mn(1), six equivalent Mn(3), and nine equivalent Mn(4) atoms. In the third Mn site, Mn(3) is bonded in a 12-coordinate geometry to two equivalent Mn(2), five equivalent Mn(4), and six equivalent Mn(3) atoms. In the fourth Mn site, Mn(4) is bonded in a 12-coordinate geometry to one Mn(1), three equivalent Mn(2), three equivalent Mn(4), and five equivalent Mn(3) atoms.
Mn is alpha structured and crystallizes in the cubic I-43m space group. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 16-coordinate geometry to four equivalent Mn(2) and twelve equivalent Mn(4) atoms. All Mn(1)-Mn(2) bond lengths are 2.80 Å. All Mn(1)-Mn(4) bond lengths are 2.85 Å. In the second Mn site, Mn(2) is bonded in a 16-coordinate geometry to one Mn(1), six equivalent Mn(3), and nine equivalent Mn(4) atoms. There are three shorter (2.59 Å) and three longer (3.09 Å) Mn(2)-Mn(3) bond lengths. There are six shorter (2.76 Å) and three longer (2.97 Å) Mn(2)-Mn(4) bond lengths. In the third Mn site, Mn(3) is bonded in a 12-coordinate geometry to two equivalent Mn(2), five equivalent Mn(4), and six equivalent Mn(3) atoms. There are a spread of Mn(3)-Mn(4) bond distances ranging from 2.43-2.68 Å. There are two shorter (2.68 Å) and four longer (2.75 Å) Mn(3)-Mn(3) bond lengths. In the fourth Mn site, Mn(4) is bonded in a 12-coordinate geometry to one Mn(1), three equivalent Mn(2), three equivalent Mn(4), and five equivalent Mn(3) atoms. There is one shorter (2.40 Å) and two longer (2.46 Å) Mn(4)-Mn(4) bond lengths.
