A rare supramolecular assembly involving ion pairs of coordination complexes with a host–guest relationship: synthesis, crystal structure, photoluminescence and thermal study

Biochemical Capacitance of Geobacter Sulfurreducens Biofilms

“…The rational design, synthesis and assembly of functional materials by supramolecular synthons is an area of widespread attention 4–7. The effective strategies of crystal engineering are based on a detailed understanding of the way non‐covalent interactions interact, compete and guide the assembly of discrete building blocks (such as ligand,8 anion9 and guest molecules10) into extended solid‐state architectures 11–13. Not only is it important to identify distinct intermolecular interactions that can link neighboring blocks into extended networks with well‐defined connectivities, it is also necessary to establish the conditions under which these interactions can be sustained, even in the presence of competing intermolecular interactions, also affect the final results.…”

The Length of Substituents on Ligands Regulates the Structural Diversity of Coordination Polymers

“…Compared with BTC, L n (n = 1, 2, 3) ligands have a qualitative effect on the structure: (і) L n ligands have an effect on the guest molecules of the complexes, which make them change from L 1 ligands in complex I to water molecules in complexes II and III; (іi) the size and shape of the A and B rings changes greatly. In the structure of I, ring A and ring B are obviously rectangular, and in the same plane, the sizes are 7.1646(35) × 3.2877 (26) 35)°( Fig. 6d).…”

“…In addition, carboxylic groups form highly unstable bonds with a series of metal cations, which is conducive to the formation of highly ordered, thermodynamic driven MOF structure rather than kineticallyfavoured amorphous by-product [23]. In this regard, 1,3,5-benzenetricarboxylic acid (H 3 BTC) as a wellknown rigid ligand has yielded a large number of coordination polymers with fascinating structural features [24][25][26][27]. The three carboxyl groups of H 3 BTC were evenly distributed around the benzene ring.…”

3D supramolecular networks of Mn(II)-5-sulfosalicylate assembled with 4,4′-dipyridyl N,N′-dioxide and 4,4′-dipyridyl: Structure, photoluminescence and DFT calculations

“…In the area of crystal engineering, the professed goal is the designed synthesis of crystalline materials where the molecular organization in the solid state can be reliably predicted from the knowledge of tectons. The principle of designed synthesis of crystalline functional materials to some extent has been rationalized, but a multitude of factors, especially weak forces such as H-bonding [20][21][22][23][24][25][26], p-p [27][28][29][30][31] and C-HÁ Á Áp interactions [32,33], are often involved, and accurate prediction of the outcome of the crystallization process is object of study. In this respect, it is interesting to elucidate the role of weak interactions in crystal packing when a number of them are simultaneously operative.…”
