Materials Data on Ba3Np by Materials Project
Ba3Np is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded to four equivalent Ba and four equivalent Np atoms to form a mixture of distorted edge, face, and corner-sharing BaBa4Np4 tetrahedra. All Ba–Ba bond lengths are 4.17 Å. All Ba–Np bond lengths are 4.17 Å. In the second Ba site, Ba is bonded in a distorted body-centered cubic geometry to eight equivalent Ba atoms. Np is bonded in a body-centered cubic geometry to eight equivalent Ba atoms.
