Designed Synthesis of POM–Organic Frameworks from {Ni₆PW₉} Building Blocks under Hydrothermal Conditions

Abstract

Directed combination of {Ni6PW9} building blocks with various rigid carboxylate linkers under hydrothermal conditions yields a series of unprecedented polyoxometalate–organic frameworks (POMOFs) with remarkable structural diversity including 1D, 2D, and 3D structures based on monomers, dimers, or infinite helical chains (see picture for 3D structure: WO6: red; NiO6: green; PO4: yellow; 1,2,4-benzenetricarboxylate: gold).
