Structural and Gas Uptake Studies on Iron(II) β‑Diketiminate Metallomacrocycles.

Abstract

Three iron metallomacrocycles were synthesized and characterized using single crystal X-ray crystallography. Varying the amide coligand allows for macrocycles containing three, four, or six iron centers. The metallomacrocycles show extended structures in the solid state that are reminiscent of metal-organic framework structures; thus, the adsorbative properties of the complexes in the solid state have been investigated using N2. Based on the data, three metallomacrocyles display classical type II isotherms and pore size distributions synonymous with mesoporous materials.
