title: 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 m(2)/g. The stability of the larger zinc cluster and the effect of the nitro group on gas sorption are also studied.
