A new decavanadate polyoxovanadate nanocluster, [2-ampH](6)[V10O28].2H(2)O (1), was synthesized through reaction between ammonium vanadate and 2-aminopyridine at pH=2. Nanocluster 1 was characterized by IR, elemental analysis, and X-ray crystallography. 1 was found to adsorb and desorb dyes and may have widespread application in wastewater treatment. The utility of 1 for adsorption of methylene blue was studied. The adsorbed dyes can be easily desorbed, and 1 has full efficiency after five cycles.
