Crystallization of phosphomolybdate clusters mediated by copper azole complexes: Influence of pH and temperature

► Formation of new copper imidazole, imi/pyrazole, pz complex based phosphomolybdates. ► Structural features - water clusters, supramolecular isomers, pseudopolymoprhs. ► Influence of pH and temperature (T) on the growth of solids. ► With an increase in pH and T, imi favored reduction of metal centers. ► Use of pz as a ligand resulted in only two oxidized solids.
