These compounds have {M [(PO4) 4 Mo6 O15] 2} dimer units and the dimers of compounds 2 to 4 form a three-dimensional network structure by hydrogen bonding with organic molecules and water molecules. The { The Co [(PO4) 4 Mo6O15] 2} dimer is composed of [CoH3 TEATA] groups and CoO4 tetrahedra, respectively. The characteristic vibrational frequencies of phosphomolybdates were related to the structures of these compounds. The three UV VisDRS bands of the compounds belong to charge transfer of Od → Mo, O → Mo and O → M, respectively. A strong fluorescence emission band excited by the transition of Oμ → Mo appears near 10nm.
