Development of a New Heteropolyoxotantalate Cluster for Multidimensional Polyoxotantalate Materials

A unique heteropolyoxotantalate (hetero-POTa) cluster[P2O7Ta5O14](7-) (P2Ta5) was first developed using pyrophosphateasa key to open the ultrastable skeleton of the classical Lindqvist-type[Ta6O19](8-) precursor. TheP(2)Ta(5) cluster can serve as a general and flexiblesecondary building unit to create a family of brand-new multidimensionalPOTa architectures. This work not only promotes the limited structuraldiversity of hetero-POTa but also provides a practical strategy fornew extended POTa architectures.

Automated summary

A unique heteropolyoxotantalate (HPOTa) cluster of [P2O7Ta5O14](7-) (P2Ta5) was first developed as a key to unlock the ultrastable skeleton of the classical Lindqvist-type [Ta6O19](8-) precursor. The P(2)Ta(5) cluster can be used as a versatile secondary building unit to create new multidimensional POTa architectures. This work not only expands the structural diversity of hetero-POTa, but also offers a practical strategy for developing extended POTa materials.
