Transformation from [W6O19](2-) to [W6O22](8-) stabilized by Cu(II) complexation.
A rare [W6O22](8-) fragment has been first captured in aqueous solution of [W6O19](2-) by using a transition-metal complex and isolated as a new compound [Cu4(W6O22)(L1)2(H2O)2]·2H2O (1; L1 = 2-amino-4,6-bis(2-pyridyl)pyrimidine), indicating that [W6O19](2-) could also transform to [W6O22](8-) in aqueous solution besides the earlier proven ψ-metatungstates, [W10O32](4-), β-[(H2)W12O40](6-) and [W7O24](6-).
