NpMn2O5F8NpOF4 is Indium-like structured and crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of two NpMn2O5F8 clusters and two NpOF4 clusters. In each NpMn2O5F8 cluster, Np(2) is bonded in a 7-coordinate geometry to one O(2), two equivalent F(4), two equivalent F(5), and two equivalent F(6) atoms. Mn(1) is bonded in a tetrahedral geometry to one O(3), one O(4), one F(2), and one F(6) atom. There are three inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one Np(2) atom. In the second O site, O(3) is bonded in a single-bond geometry to one Mn(1) atom. In the third O site, O(4) is bonded in a single-bond geometry to one Mn(1) atom. There are four inequivalent F sites. In the first F site, F(2) is bonded in a distorted single-bond geometry to one Mn(1) atom. In the second F site, F(4) is bonded in a single-bond geometry to one Np(2) atom. In the third F site, F(5) is bonded in a single-bond geometry to one Np(2) atom. In the fourth F site, F(6) is bonded in a distorted single-bond geometry to one Np(2) and one Mn(1) atom. In each NpOF4 cluster, Np(1) is bonded in a distorted square pyramidal geometry to one O(1), two equivalent F(1), and two equivalent F(3) atoms. O(1) is bonded in a single-bond geometry to one Np(1) atom. There are two inequivalent F sites. In the first F site, F(3) is bonded in a single-bond geometry to one Np(1) atom. In the second F site, F(1) is bonded in a single-bond geometry to one Np(1) atom.
