The synthetic opportunities furnished by organic synthesis and the inherent structure-directing possibilities of coordination complexes have been combined in the assembly of a series of layered metal-containing hybrid materials. The supramolecular assembly relies on self-complementary non-covalent interactions, and in five of the six structures presented herein, N–H···O=C hydrogen bonds between acetamide moieties on neighbouring ligands provide the primary structure-direction tool as intended. The distances between metal ions are controlled by ligand···ligand hydrogen bonds and reside within a narrow and tuneable range. The following crystal structures are reported: [Cu(4-(3-pyridyl)-1-acetamidobenzene)2(1,1,1,5,5,5-hexafluoro-2,4-pentanedione)2] 1; [Cu(4-(acetamidomethyl)pyridine)2(1,1,1,5,5,5-hexafluoro-2,4-pentanedione)2]·2CH2Cl2 2; [Cu(3-acetamidopyridine)2(1,1,1,5,5,5-hexafluoro-2,4-pentanedione)2] 3; [Ni(3-acetamidopyridine)2(1,3-diphenyl-1,3-propanedione)2]·2CH2Cl2 4; [Ni(3-acetamidopyridine)2(1,3-diphenyl-1,3-propanedione)2] 5; and [Co(2-acetamidopyridine)2(1,3-diphenyl-1,3-propanedione)2]·2CH2Cl2 6.

AbstractDynamic constitutional hybrid materials in which the functional self-organized macrocycles are reversibly connected with the inorganic silica mesopores through hydrophobic non-covalent interactions. Supramolecular columnar self-organized architectures confined within scaffolding hydrophobic silica mesopores can be structurally determined by using X-ray diffraction techniques.

<div> <div> <div> <p>Metal-organic frameworks offer a convenient means for capturing, transporting, and releasing small molecules. Rational design of such systems requires an in-depth understanding of the underlying non-covalent interactions, and the ability to easily and rapidly pre-screen candidate architectures in silico. In this work, we devised a recipe for computing the strength and analysing the nature of the host-guest interactions in MOFs. Using experimentally characterised complexes of calcium-adipate framework with 4,4’-bipyridine and 1,2-bis(4-pyridyl)ethane guests as test systems, we have assessed a range of density functional theory methods, energy decomposition schemes, and non-covalent interactions indicators across realistic periodic and finite supramolecular cluster scales. We find that appropriately constructed clusters readily reproduce the key interactions occurring in periodic models at a fraction of the computational cost and with an added benefit of diverse density partitioning schemes. Host-guest interaction energies can be reliably computed with dispersion- corrected density functional theory methods; however, decoding their precise nature demands insights from energy decomposition schemes and quantum-chemical tools beyond local bonding indices (e.g., the quantum theory of atoms in molecules), such as the non-covalent interactions index and the density overlap regions indicator. </p> </div> </div> </div>
