Na7SbO6 crystallizes in the trigonal R3 space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one O(2) and three equivalent O(1) atoms. In the third Na site, Na(3) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Sb(1) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Na(1), one Na(3), three equivalent Na(2), and one Sb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Na(2), one Na(3), three equivalent Na(1), and one Sb(1) atom.
