Two binuclear Ni-inserted polyoxotantalates based on {NiTa₁₀O₃₂} units with catalytic activity

Abstract

Two cases of hetero-polyoxotantalates containing {NiTa10} are reported for the first time. Ni as a heteroatom is located in the center of the {Ta10} unit. And 2 exhibits excellent catalytic performance in transesterification reactions.
