A new compound, Na(HINA) 2 (NH 4 ) 2 [PMo 10 V 2 O 40 ] · 14H 2 O ( 1 ) (INA = isonicotinic acid) was synthesized and characterized structurally by elemental analysis, IR spectroscopy, and TG. Bisubstituted molybdovanadophosphate anions have typical Keggin anion structure and are linked weakly by Na + ions into an anionic chain along crystallographic b axis. Protonated INA cations form another supramolecular cationic chain also along crystallographic b axis. Two chains, water molecules, and ammonium ions form the 3D supramolecular architecture through hydrogen bonds. The compound has an excellent catalytic activity to starch oxidation. The detailed study gives optimum reaction condition.
