A Graphite-Like Complex with Large Cavities Constructed with the Complex Ligand [NiII(bpca)2]

Interpenetration is avoided in the graphite-like structure constructed by the complex ligand [NiII(bpca)2] (bpca=bis(2-pyridylcarbonyl)amine) and iron(II) ions (see picture). The structure contains large cavities at the centers of the rings. Controlling the reaction stoichiometry and the choice of solvents enables this complex to be prepared selectively in preference to related discrete trinuclear and one-dimensional complexes.
