Zr(iv) and Hf(iv) based metal–organic frameworks with reo-topology

Abstract

Zr and Hf based MOFs with enhanced pore accessibility for large molecules and good hydrothermal stability were obtained using a bent dithienothiophene dicarboxylate and Zr⁴⁺ or Hf⁴⁺ source. A modulator (benzoic acid) facilitates formation of an eight-connecting cluster leading to a new framework which adopts reo topology.
