Zn7O2(RCOO)(10) Clusters and Nitro Aromatic Linkers in a Porous Metal-Organic Framework

Abstract

A new metal–organic framework, CALF-22 comprising Zn7O2(COO)10 secondary building units and 2-nitro-1,4-benzenedicarboxylate, is reported. The porosity and gas adsorption of N2, H2, CO2, and CH4 are studied, and CALF-22 has a surface area in excess of 1000 m2/g. The stability of the larger zinc cluster and the effect of the nitro group on gas sorption are also studied.
