New Three-Dimensional Metal−Organic Framework with Heterometallic Fe−Ag Building Units: Synthesis, Crystal Structure, and Functional Studies

A new three-dimensional metal-organic framework (MOF) containing Fe(II) and Ag(I) ions and 2-pyrazinecarboxylic acid (pcaH) was synthesized, and its magnetic and catalytic properties were studied. The MOF has a big window size of 12.1 × 12.0 Å, with 23.8% solvent-accessible space, and shows size selectivity toward Lewis acid catalysis.
