BaSr2Np crystallizes in the cubic F-43m space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Sr(1) and four equivalent Np(1) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ba(1) and four equivalent Sr(2) atoms. In the second Sr site, Sr(2) is bonded to four equivalent Sr(1) and four equivalent Np(1) atoms to form distorted edge-sharing SrSr4Np4 tetrahedra. Np(1) is bonded in a body-centered cubic geometry to four equivalent Ba(1) and four equivalent Sr(2) atoms.
