Salts of the pararosaniline dye cation and four polyoxometalate cluster anions have been isolated under both ambient and hydrothermal conditions; structural and initial spectroscopic data are consistent with significant perturbation of ion electronic states induced by charge-assisted N-H---O hydrogen bonds.
