The structure described by NaBO7 crystallizes in the triclinic P-1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted octahedral geometry to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to two equivalent O(3), two equivalent O(5), and two equivalent O(7) atoms. B(1) is bonded in a trigonal planar geometry to one O(2), one O(6), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one O(3) and one O(4) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one B(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Na(2) and one O(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one Na(1) and one O(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to one Na(2), one O(6), and one O(7) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Na(1), one B(1), and one O(5) atom. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to one Na(2), one B(1), and one O(5) atom. is represented by the Crystallographic Information File (CIF) [CIF]
