2D Layered metal–organic frameworks built using a hexanuclear metallamacrocycle and an octanuclear metallamacrocycle as supramolecular building blocks

Abstract

Two different 2D layered metal–organic frameworks (MOFs) have been prepared using a hexanuclear manganese metallamacrocycle and an octanuclear manganese metallamacrocycle as supramolecular building blocks via a simple change of the solvent used and/or addition of a templating agent. While the sheets in the 2D MOF [Mn₆(pshz)₆(bpea)₂(dma)₂]_n, 2 (where, pshz³⁻ is N-propionylsalicylhydrazidate, bpea is 1,2-bis(pyridyl)ethane, and dma is N,N-dimethylacetamide), built based on a hexanuclear metalladiazamacrocycle are in a staggered orientation, the sheets in the 2D MOF [Mn₈(pshz)₈(bpea)₂(dma)₄]_n, 3, built based on an octanuclear metalladiazamacrocycle are in an eclipsed orientation. However, both MOFs have the same 3-connected 4.8² network topology.
