Descreeption

Ball-and-stick model of the unit cell of borax ("sodium tetraborate decahydrate"), Na2B4O7·10H2O, better described as Na2[B4O5(OH)4]·8H2O. Boron is pink, oxygen is red, hydrogen is white, and sodium is lilac. The structure includes 8 water molecules for each tetraborate anion (not shown, for clarity).

Neutron diffraction data from H. A. Levy and G. C. Lisensky (December 1978). "Crystal structures of sodium sulfate decahydrate (Glauber's salt) and sodium tetraborate decahydrate (borax). Redetermination by neutron diffraction". Acta. Cryst. B 34 (12): 3502-3510. DOI:10.1107/S0567740878011504.

The anion's formula is [ B4O5(OH)42- ]. A refined structure was published in

G. J. Gainsford, T. Kemmitt and C. Higham (2008): "Redetermination of the borax structure from laboratory X-ray data at 145 K". Acta Crystallographica Series E (Inorganic Compounds), volume E64, pages i24-i25. doi:10.1107/S1600536808010441

According to this source, each sodium ion is surrounded by 6 water molecules, 4 of which are shared with 4 other sodium cations, forming zigzag chains.
