A supramolecular compound of vanadium (V) with [(CH3)2NH2]4[V16O42](SO4).2(O)[+solvent] formula (1) was crystallized in the tetragonal crystal system, space group P42/nnm with Z=2. The final R value of compound 1 is 0.048 for 2214 independent reflections. The asymmetric unit of 1 consists of a half of the dimethylammonium cation, a quarter of sulfate anion, a part of vanadium cluster, and water molecules. In the supramolecular structure of compound 1, each dimethyl ammonium cation is bridged between two polyoxovanadate clusters through hydrogen bonds and sulfate anions play a key role as the tetragonal supramolecular structure extends along these anions.
