The crystal structure described by NaV13O18 crystallizes in the trigonal R-3 space group. The structure consists of three 7440-23-5 atoms inside a V13O18 framework. In the V13O18 framework, there are three inequivalent V sites. In the first V site, V(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 10-16°. In the second V site, V(2) is bonded to one O(1), two equivalent O(3), and three equivalent O(2) atoms to form a mixture of edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 8-10°. In the third V site, V(3) is bonded to six equivalent O(3) atoms to form a mixture of edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one V(2) and three equivalent V(1) atoms. In the second O site, O(2) is bonded to two equivalent V(1) and three equivalent V(2) atoms to form a mixture of edge and corner-sharing OV5 square pyramids. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one V(1), one V(3), and two equivalent V(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
