Water-based synthesis and characterisation of a new Zr-MOF with a unique inorganic building unit

Abstract

A new, microporous Zr-MOF was obtained using 2,5-pyrazinedicarboxylic acid (H2PzDC). The linker leads to the formation of a new 1D inorganic building unit composed of μ-OH bridged {Zr6O4(OH4)} clusters which are arranged in a hexagonal array and connected by the PzDC2− ions. The structure was determined from powder X-ray diffraction data.
