A crown-shaped organic鈥搃norganic hybrid polyoxomolybdate, Na5[H7{N(CH2PO3)3}Mo6O16(OH) (H2O)4]4路18H2O (1) has been presented and characterized. Such an intriguing structure consists of a 24-molybdenum-membered polyanion constructed by organotriphosphonate ligands, which represents the highest nuclearity of metal atoms in the area of organophosphonate-based polyoxometalates.
