Abstract
AbstractThe hexanuclear manganese metallamacrocycle [Mn6(Haahz)6(dmso)6] (1) was prepared by using a new pentadentate ligand, N‐acetylaminobenzhydrazide (H4aahz), and a manganese ion as primary building blocks in dimethyl sulfoxide (dmso). Under identical conditions but in the presence of 1,2‐bis(4‐pyridyl)ethane (bpea) as an exo‐bidentate linker in dimethylformamide (dmf), the 2D layered metal–organic framework (MOF) [Mn6(Haahz)6(bpea)2(dmf)2]n (2) was obtained, where the hexanuclear manganese metallamacrocycle served as a supramolecular building block. The network topology of 2, a 3‐connected 4.82 topology, is quite different from those of the MOFs obtained from a similar pentadentate ligand, N‐acylsalicylhydrazide, although the same hexanuclear manganese metallamacrocycles were used as supramolecular building blocks and bpea was used as the same linker ligand. Although the layers of 2 are staggered relative to each other, the network has quite a large solvent cavity between the layers, because of the corrugated nature of the layer.(© Wiley‐VCH Verlag GmbH & Co.
