The structure described by Na2VO3 crystallizes in the orthorhombic Cmc2_1 space group. Na(1) is bonded to one O(1) and four equivalent O(2) atoms to form NaO5 trigonal bipyramids that share corners with four equivalent V(1)O4 tetrahedra, corners with five equivalent Na(1)O5 trigonal bipyramids,  an edgeedge with one V(1)O4 tetrahedra, and edges with four equivalent Na(1)O5 trigonal bipyramids. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with two equivalent V(1)O4 tetrahedra, corners with eight equivalent Na(1)O5 trigonal bipyramids, and edges with two equivalent Na(1)O5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1) and two equivalent V(1) atoms to form distorted ONa2V2 trigonal pyramids that share corners with eight equivalent O(2)Na4V trigonal bipyramids, corners with two equivalent O(1)Na2V2 trigonal pyramids, and edges with two equivalent O(2)Na4V trigonal bipyramids. In the second O site, O(2) is bonded to four equivalent Na(1) and one V(1) atom to form distorted ONa4V trigonal bipyramids that share corners with five equivalent O(2)Na4V trigonal bipyramids, corners with four equivalent O(1)Na2V2 trigonal pyramids, edges with four equivalent O(2)Na4V trigonal bipyramids, and  an edgeedge with one O(1)Na2V2 trigonal pyramid. is represented by the CIF file [CIF]
