Self-assembly of catalytically-active supramolecular coordination compounds within metal-organic frameworks (J. Am. Chem. Soc. 2019, 141, 26, 10350-10360)

Supramolecular Coordination Compounds (SCCs) represent the power of Coordination Chemistry methodologies to self-assemble discrete architectures with targeted properties. SCCs are generally synthesised in solution, with isolated fully-coordinated metal atoms as structural nodes, thus severely limited as metal-based catalysts. Metal-Organic Frameworks (MOFs) show unique features to act as chemical nanoreactors for the in-situ synthesis and stabilization [...]

Magnetic order in a CuII-DyIII oxamato-based two-dimensional coordination polymer (C. R. Chimie 22 (2019) 466-475)

We report the synthesis, crystal structure and magnetic characterization of a novel two-dimensional copper(II)-dysprosium(III) coordination polymer of formula [LiI(OH2)4]2[DyIIICuII2(Me2pma)4Cl(H2O)] . 4H2O (1) [Me2pma = N-2,6-dimethylphenyloxamate]. Compound 1 was obtained by using the mononuclear anionic complex, [CuII(Me2pma)2]2-, as a bis(bidentate) metalloligand toward solvated dysprosium(III) cations and shows a square [DyIIICuII2] layered structure of (44.62) net topology. [...]

Efficient Gas Separation and Transport Mechanism in Rare Hemilabile Metal-Organic Framework (Chem. Mater. 2019, 31, 15, 5856-5866)

Understanding/visualizing the established interactions between gases and adsorbents is mandatory to implement better performance materials in adsorption/separation processes. Here we report the unique behavior of a rare example of a hemilabile chiral three-dimensional metal-organic framework (MOF) with an unprecedented qtz-e-type topology, with formula CuII2(S,S)-hismox·5H2O (1) (hismox = bis[(S)-histidine]oxalyl diamide). 1 exhibits a continuous and reversible [...]

Multivariate Metal-Organic Frameworks for the Simultaneous Capture of Organic and Inorganic Contaminants from Water (J. Am. Chem. Soc. 2019, 141, 34, 13601-13609)

We report a new water-stable multivariate (MTV) Metal-Organic Framework (MOF) prepared by combining two different oxamide-based metalloligands derived from the natural amino acids L-serine and L-methionine. This unique material features hexagonal channels decorated with two types of flexible and functional 'arms' (-CH2OH and -CH2CH2SCH3) capable to act, synergistically, for the simultaneous and efficient removal of [...]

Metal−Organic Frameworks as Playgrounds for Reticulate Single-Molecule Magnets (Inorg. Chem. 2019, 58, 21, 14498-14506)

Achieving an accurate control on the final structure of Metal-Organic Frameworks (MOFs) is mandatory to obtain target physical properties. Here we describe how the combination of a metalloligand design strategy and a post-synthetic method is a versatile and powerful approach to success on this extremely difficult task. In a first stage, a novel oxamato-based tetranuclear [...]
