Na3WO3N is beta beryllia-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to one N(1), one O(1), and two equivalent O(2) atoms to form NaNO3 tetrahedra that share corners with four equivalent Na(1)NO3 tetrahedra, corners with four equivalent Na(2)NO3 tetrahedra, and corners with four equivalent W(1)NO3 tetrahedra. In the second Na site, Na(2) is bonded to one N(1), one O(1), and two equivalent O(2) atoms to form NaNO3 tetrahedra that share corners with four equivalent W(1)NO3 tetrahedra and corners with eight equivalent Na(1)NO3 tetrahedra. W(1) is bonded to one N(1), one O(1), and two equivalent O(2) atoms to form WNO3 tetrahedra that share corners with four equivalent Na(2)NO3 tetrahedra and corners with eight equivalent Na(1)NO3 tetrahedra. N(1) is bonded to one Na(2), two equivalent Na(1), and one W(1) atom to form NNa3W tetrahedra that share corners with four equivalent O(1)Na3W tetrahedra and corners with eight equivalent O(2)Na3W tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(2), two equivalent Na(1), and one W(1) atom to form distorted ONa3W tetrahedra that share corners with four equivalent N(1)Na3W tetrahedra and corners with eight equivalent O(2)Na3W tetrahedra. In the second O site, O(2) is bonded to one Na(2), two equivalent Na(1), and one W(1) atom to form ONa3W tetrahedra that share corners with four equivalent N(1)Na3W tetrahedra, corners with four equivalent O(1)Na3W tetrahedra, and corners with four equivalent O(2)Na3W tetrahedra.
