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.
