Non-covalent interactions in organic-inorganic hybrid compounds derived from amino amides

Indium Coordination Compounds Derived from Amino Amides

“…Thus, the mixture of compounds 1 c – 8 c in deionized water and the subsequent elimination of the solvent (using an air stream) caused the appearance of an additional band at 1692–1663 cm −1 in all IR spectra. The vibration frequency of this signal is similar to reported values for carbonyl groups in the completely diprotonated amino amides [1694–1662 cm −1 ] [26] . Moreover, the IR spectra presented a new broadband between 3600 and 2650 cm −1 corresponding to a water molecule coordinated to the metal ion and molecules of dissolvent participating in supramolecular networks [27] .…”

“…The vibration frequency of this signal is similar to reported values for carbonyl groups in the completely diprotonated amino amides [1694-1662 cm À 1 ]. [26] Moreover, the IR spectra presented a new broadband between 3600 and 2650 cm À 1 corresponding to a water molecule coordinated to the metal ion and molecules of dissolvent participating in supramolecular networks. [27] These results are concordant with the thermogravimetric studies and elemental analysis, which showed that the coordination compounds tend to capture solvent molecules and that the N!In coordination is kept in an aqueous solution (see supporting material).…”

A multifunctional [CdI4]2−·[H2Bimb]2+complex to probe high performance photocatalytic degradation of methyl violet and fluorescent detection of Cr2O72−and Hg2+ions

“…Non-covalent interactions including p-p stacking, hydrogen bonding, and van der Waals contacts can also have an impact on the final network structure and stability. 18 One of the biggest issues faced by human society today is environmental degradation, which puts our ecological and physical well-being in grave peril. The textile, printing, paper, food, cosmetic, and pharmaceutical industries all use carcinogenic organic dyes, which are highly widespread organic contaminants.…”

The Effects of pH on the Supramolecular Structure of Amino Amides

“…[2] The presence of histidine residues in proteins is relevant because imidazole groups can form extensive networks of hydrogen bonds that can be modulated by the pH of the medium. [9][10][11][12][13][14] For this reason, the design of abiotic molecules with imidazole groups is chemically relevant. In this context, we hypothesize that it is possible to modulate the molecular aggregation of amino amides by controlling the system's pH.…”

“…In contrast, dipeptides with hydrophobic chains (such as di‐leucine, di‐isoleucine, and di‐valine) preferentially generate microporous materials [2] . The presence of histidine residues in proteins is relevant because imidazole groups can form extensive networks of hydrogen bonds that can be modulated by the pH of the medium [9–14] . For this reason, the design of abiotic molecules with imidazole groups is chemically relevant.…”
