Abstract

The structure of [B6H9NaO14, H3BO3, 6H(2)O] was determined by single-crystal X-ray diffraction and further analyzed by FTIR spectroscopy and differential thermal/thermogravimetric analysis. The asymmetric unit contains Na-O polyhedra (distorted octahedron), [B6O8(OH)(3)](-) fundamental building blocks, one free water molecule and one free H3BO3 molecule. In the hexaborate anion, three B3O3 rings are linked by a common oxygen atom with five trigonal and one tetrahedral boron atoms. The hexaborate group is also linked to the oxygenated environment of the sodium atom by three other six-membered rings, each of which involve two boron atoms, three oxygen atoms, and sodium as the joint atom.
