• The crystal structure of sodium hexahydroxoantimonate (V), NaSb(OH)<SUB>6</SUB>, has been refined. The previous structure given by Schrewelius was confirmed, but the positional parameters of oxygen atoms were shifted significantly. Both antimony and sodium atoms are surrounded by six oxygen atoms octahedrally. The interatomic distances are: Sb–O=1.972–1.999 Å (mean 1.98 Å), O–O=2.758–2.834 Å (2.80 Å) for an SbO<SUB>6</SUB> octahedron, Na–O=2.375–2.406 Å (2.39 Å) and O–O=3.229–3.526 Å (3.38Å) for an NaO<SUB>6</SUB> octahedron. Two types of sequences of hydrogen bonds were recognized. They were compared with the sequences of hydrogen bonds in In(OH)<SUB>3</SUB> and MnSn(OH)<SUB>6</SUB>.
