Materials Data on NpMn2 by Materials Project
NpMn2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Np is bonded in a 12-coordinate geometry to four equivalent Np and twelve equivalent Mn atoms. All Np–Np bond lengths are 3.01 Å. All Np–Mn bond lengths are 2.88 Å. Mn is bonded to six equivalent Np and six equivalent Mn atoms to form a mixture of face, edge, and corner-sharing MnNp6Mn6 cuboctahedra. All Mn–Mn bond lengths are 2.46 Å.
