Abstract
Two new compounds based on Anderson-type polyanions, H(C6H9N3O2)2[Mn(H2O)2][Al(OH)6Mo6O18] ⋅ 6H2O (1) and (C6H10N3O2)2[Ag(H2O)2][Cr(OH)6Mo6O18] ⋅ 6H2O (2), have been synthesized in aqueous solution and characterized by elemental analyses, IR, TG, and single crystal X-ray diffraction. Both compounds show inorganic 1-D chain-like structures in which the Anderson-type polyanions are bidentate ligands chelating to two metal cations. Further, transition metal cations are in the same line with the center Al (Cr), which is unusual in 1-D inorganic chains based on Anderson-type polyanions. Free histidine molecules further link the chains into 3-D supramolecular frameworks via hydrogen interactions. Electrochemical and fluorescence quenching properties were investigated.
