The compound described by KNp2F9 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 10-coordinate geometry to two equivalent F(1), two equivalent F(2), two equivalent F(3), and four equivalent F(5) atoms. Np(1) is bonded in a 9-coordinate geometry to one F(4), two equivalent F(1), two equivalent F(2), two equivalent F(3), and two equivalent F(5) atoms. There are five inequivalent F sites. In the first F site, F(4) is bonded in a linear geometry to two equivalent Np(1) atoms. In the second F site, F(5) is bonded to two equivalent K(1) and two equivalent Np(1) atoms to form a mixture of distorted corner and edge-sharing FK2Np2 tetrahedra. In the third F site, F(1) is bonded in a distorted bent 150 degrees geometry to one K(1) and two equivalent Np(1) atoms. In the fourth F site, F(2) is bonded in a trigonal planar geometry to one K(1) and two equivalent Np(1) atoms. In the fifth F site, F(3) is bonded in a trigonal planar geometry to one K(1) and two equivalent Np(1) atoms. is represented by the CIF file [CIF]
