The structure described by Na2VO3 is Krennerite-derived structured and crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. V(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted edge-sharing VO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent Na(1) and one V(1) atom. In the second O site, O(2) is bonded to four equivalent Na(1) and two equivalent V(1) atoms to form a mixture of distorted face, corner, and edge-sharing ONa4V2 octahedra. The corner-sharing octahedral tilt angles range from 38-52°. is represented by the Crystallographic Information File (CIF) [CIF]
