Two 3D metal-organic frameworks (MOFs) with a new biphenol-derived tetracarboxylate linker and Cu-II and Zn-II metal-connecting points were synthesized and characterized by single-crystal X-ray crystallographic studies. The two isostructural MOFs exhibit distorted PtS network topology and show markedly different framework stability. The porosity and hydrogen uptake of the frameworks were determined by gas adsorption experiments.
