Abstract

Our conceived approach based on the directed assembly of functional metal-organic squares (MOSs), 4-membered ring (4MR) building units, permitted the construction of two novel zeolite-like supramolecular assemblies (ZSAs), namely [Co 4 (ImDC) 4 (En) 4 ]·9H 2 O·1.5DMF ( ZSA-10 ) and [Co 4 (ImDC) 4 (En) 4 ]·7H 2 O ( ZSA-11 ) (H 3 ImDC = 4,5-imidazoledicarboxylic acid, En = ethylenediamine, DMF = N,N-dimethylformamide). The elected MOSs encompass both trans - and cis -coordinated nodes, offering complementary peripheral functional groups for their directed assembly into zeolite-like topologies via supramolecular hydrogen bonding interactions. Distinctly, ZSA-10 possesses the underling MER zeolite topology and is the only pure MER framework material (without any supporting templates) exhibiting permanent porosity up to now. ZSA-11 has the underlying ABW topology together with one type of narrow channel.
