Abstract

Two high-nuclear wheel-shaped nanoscale clusters, [Co(H₂O) ₆]{[C₃H₄N₂]₂[C ₅NH₅]₁₄[H₁₅(Mo₂O ₄)₈Co₁₆(PO₄)₁₄(HPO ₃)₁₀(OH)₃]}·5H₂O (1) and [C₃H₅N₂]₄[C₅NH ₅]₂[Ni(H₂O)₆]{[C₃H ₄N₂]₂[C₅NH₅] ₁₄[H₁₈(Mo₂O₄)₈Ni ₁₆(PO₄)₂₂(OH)₆]}·11H ₂O (2), have been successfully synthesized employing the Py and Imi ligands as chemical modifiers. Both clusters take nanoscale wheel-like shapes, and the inorganic cores are wrapped up by the Py and Imi ligands acting as organic shells. In compounds 1 and 2, the polyoxoanion unit exhibits a new organic-inorganic hybrid polymolybdophosphate, representing the first two isolated POMs in the wheel-type {Mo/TM/P} materials, while Py and Imi ligands improve electric the delocalization effects of polyanions. It is worth noting that the molecular TPA cross section σ of compound 1 is 2.5 times that of compound 2, which demonstrates that the nonlinear optical property can also be improved by replacing part of the phosphate radicals with phosphite radicals through enhancing electron delocalization.
