“…The Ag–C bonding is not unusual. References widely reported Ag–C bond lengths in the range of 2.388(5)–2.763(3) Å in Ag(I) polymers for benzene ring C–Ag bonds. − As for Ag(2), it is five coordinated with five oxygen atoms (O3, O5, O5#, O6, O7) from five Hbtec 3– ligands forming a slightly distorted trigonal bipyramid coordination sphere, and the O5, O6, O7, and Ag2 are almost coplanar with only 0.0157 Å off the mean plane. The O3 and O5 occupy the two vertex positions of the trigonal bipyramid coordination sphere.…”

Three novel silver(I) metal−organic coordination polymers constructed from 1,2,3,5-benzenetetracarboxylic acid with different deprotonation degrees, namely, [Ag 2 (H 2 btec)(H 2 O)] (1), [Ag 3 (Hbtec)] (2), and [Ag 4 (btec)](3) (H 4 btec = 1,2,3,5-benzenetetracarboxylic acid), have been synthesized with hydrothermal methods and characterized by elemental analysis, infrared, thermogravimetric analysis, and single crystal X-ray diffraction. The Ag(I) atoms show versatile coordination sphere in the three different complexes and great supramolecular structure difference demonstrated due to the coordination modes change of the H 4 btec ligands. Ag(I) dimers bridged by H 2 btec 2− ligands into a three-dimensional framework was observed in complex 1. An unprecedented talon-like Ag(I) hexamer unit was obtained in complex 2, which acts as a building unit that connects with Hbtec 3− into (5,10)-connected MoGe 2 -type framework. A one-dimensional Ag(I) chain built with Ag(I) tetramer units was demonstrated in complex 3, and each btec 4− ligand bridges six such chains into a three-dimensional framework. However, the weaker argentophilic interactions bridge the talon-like hexamers into a bead-like Ag(I) chain in complex 2, while such weak interactions bridge the zigzag Ag(I) chains into a two-dimensional Ag(I) sheet in complex 3. Photoluminescence, and antibacterial activities of complexes 1−3 were also examined.

“…In the case of AgMOF-S1, the formation of a composite rather than of a physical mixture of the components is supported by the total absence of the four bands at 1000−1180 cm −1 , characteristic of the symmetric and asymmetric stretching vibration of O=SO in −SO 3 H and sulfates. These groups, along with carboxyl groups, can easily coordinate to Ag + centers and occupy the coordination sites around these ions, 50 and thus, they are likely involved in the composite formation. Because for AgMOF-S2, the bands of O=SO are still distinguishable, they are not involved in a chemical reaction with AgMOF to the same extent as in the case of AgMOF-S1.…”

Nanocomposites and hybrid materials of Ag−1,3,5benzenetricarboxylic acid metal−organic frameworks (MOFs) with Sand N-carbon quantum dots (CQDs) were synthesized and evaluated for their antibacterial activity against representative Gram-positive (Bacillus subtilis) and Gram-negative (Escherichia coli) bacterial strains using the qualitative disk-diffusion approach and the quantitative minimum inhibitory concentration test. The composites and hybrids were found to be nontoxic to living cells. The composite formation fostered a synergistic effect that enhanced their antibacterial activity compared with those of their pristine components. Charge transfer from AgMOF to CQDs facilitated the electrostatic interactions of the composites and hybrids with the bacterial cell membranes. Enhanced bactericidal activity was linked to morphological features (a nanorod-like morphology) and specific surface chemistry. The latter affected the release of silver. Silver on the surface of the MOFs rather than silver in the bulk was found to be important. The destruction of the MOF component in the extracellular environment led to the release of silver ions, which have a high affinity to S compounds of the cell physiology. The formation of metallic silver (Ag°) and silver sulfides (Ag 2 S) was suggested as essential for the ability of the composites and hybrids to inhibit bacterial growth. To the best of our knowledge, this is the first study that introduces the bactericidal effect of AgMOF−CQDs composites and hybrids.

Treatment of a variety of zwitterionic amino‐arenesulfonic acids with silver oxide has resulted in the synthesis of seven new AgI amino‐arenesulfonates [Ag(O3SR)]∞ [R = o‐aminobenzyl (oAB) (1), m‐aminobenzyl (mAB) (2), 6‐amino‐3‐methoxybenzyl (6A3MB) (3), o‐aminonaphthyl (oAN) (4), 5‐aminonaphthyl (5AN) (5), 4‐amino‐3‐hydroxynaphthyl (4A3HN) (6) and 5‐isoquinolinyl (I) (7)]. This has allowed an exploration of their coordination chemistry, whereby we examine the impact of structural diversity in the anions: the position of the amino functionality on the arene moiety, inclusion of the N within a heterocycle and an increase in ring size from phenyl to naphthyl. The solid‐state structures of 1, 2 and two forms of 4, one with a coordinated water molecule, have been determined by X‐ray diffraction and are all polymeric. Analytical data is provided for two of the structurally known complexes: known silver p‐aminobenzenesulfonate 8 [Ag(O3SBAp)]∞ and AgI 2‐pyridinesulfonate [Ag(O3SP)]∞ (9). The composition of all nine complexes has been confirmed through NMR spectroscopy, MS‐ES+, FTIR and elemental analysis.
