Strandberg-type phosphomolybdate anions are metal-oxide clusters with general formula [HnP2Mo5O23]((6.n)) (n = 0, 1, 2). The protonation/deprotonation of this anion affects its redox properties. Herein, we explain how to select the organic counterions to direct the synthesis towards the non-protonated or protonated anion. The method is illustrated with the synthesis of two new compounds (C5H16N2)(3)[P2Mo5O23]center dot 4H(2)O (1) and (CH6N)(4)[H2P2Mo5O23]center dot CH5N center dot 4H(2)O (2). The two compounds were characterized by UV-Visible absorption, IR spectroscopy and single crystal X-ray diffraction. Their thermal stabilities and redox properties were also investigated.
