Breaking boundaries: novel tridecavanadate polyoxometalates with a unique six-fold tetradentate coordination capacity for lanthanum( iii ) and a two-fold bidentate decavanadate ligand in a single compound

For the first time, a tridecavanadate isopolyvanadate species, [VIVVV12O38]12− (V13) has been identified and synthesized via a pH-controlled slow-evaporation method yielding water-insoluble, black rod-shaped crystals of {[La(H2O)3]2[La(H2O)5]4[µ-V10O28][µ6-VIVVV12O38]}·24H2O, exhibiting a polymeric...
