From Metal−Organic Squares to Porous Zeolite-like Supramolecular Assemblies

We report the synthesis, structure, and characterization of two novel porous zeolite-like supramolecular assemblies, ZSA-1 and ZSA-2, having zeolite gis and rho topologies, respectively. The two compounds were assembled from functional metal-organic squares (MOSs) via directional hydrogen-bonding interactions and exhibited permanent microporosity and thermal stability up to 300 °C.

Directed assembly of metal-organic cubes from deliberately predesigned molecular building blocks

A novel anionic metal-organic cube (MOC-1), [Ni(8)(HImDC)(12)](8-), has been synthesized by metal-ligand directed assembly of eight tri-connected Ni nodes and twelve doubly deprotonated bis(bidentate) imidazoledicarboxylic acid ligands (HImDC).

Molecular building blocks approach to the assembly of zeolite-like metal–organic frameworks (ZMOFs) with extra-large cavities

Two novel porous anionic zeolite-like metal-organic frameworks, rho-ZMOF and sod-ZMOF, have been synthesized by metal-ligand-directed assembly of rigid and directional tetrahedral building units, InN4 synthesized in situ, and doubly deprotonated bis(bidentate) imidazoledicarboxylic acid ligands (HImDC) in the presence of different structure directing agents (SDAs).

Assembly of two 3-D metal–organic frameworks from Cd(II) and 4,5-imidazoledicarboxylic acid or 2-ethyl-4,5-imidazoledicarboxylic acid

Two new metal–organic frameworks [Cd3(H2O)2(C5N2O4H)2·H2O] 1 and [KCd(C7N2O4H5)] 2 have been hydrothermally synthesized employing 4,5-imidazoledicarboxylic acid (IMDC) and 2-ethyl-4,5-imidazoledicarboxylic acid (2-EtIMDC) as organic ligands. The single-crystal structure analysis reveals that compound 1 exhibits a 3-D framework, which is generated from 2-D layers pillared by 1-D chains along the c-axis. Compound 2 presents a 3-D structure with 1-D channels, which are connected in a cross-like fashion by [CdN2O3] trigonal bipyramid units and 2-EtIMDC ligands.
