The compound described by Np2Se2O crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Np2Se2O cluster. Np(1) is bonded in a distorted linear geometry to one Se(1) and one O(1) atom. Se(1) is bonded in a single-bond geometry to one Np(1) atom. O(1) is bonded in a linear geometry to two equivalent Np(1) atoms. is represented by the CIF file [CIF]
