Diverse stacked and entangled topologies in cadmium tricarballylate coordination polymers with nitrobenzene detection capability

Nanosized supramolecular complex (SC), {[Cu 2 (CN) 3 (phen) 3 ]5H 2 O}, 1, inlaid with silver nanoparticles was synthesized and characterized by X-ray powder diffraction (XRPD), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscope (SEM), transmission electron microscope (TEM), and inductively coupled plasma (ICP) spectroscopy. The catalytic activity of Ag/SC1 nanocomposite as heterogeneous catalysts against methylene blue (MB) dye exhibits phenomenal degradation efficiency in presence of H 2 O 2 under different conditions better than the nanosized SC1. Scavenger techniques proved that • OH radicals represent the main oxidant species for the mineralization of hazardous dyes. The photoluminescence property of Ag/SC1 nanocomposite demonstrates its remarkable ability to act as a high-performance luminescent sensor towards nitrobenzene, Fe 3+ , Hg 2+ , and Sn 2+ ions. In vitro cytotoxicity and cell viable activity of Ag/SC1 nanocomposite against a set of different human cancer cell lines shows that the highest level was recorded against hepatocellular carcinoma (HEPG-2) cells. DNA binding ability of Ag/SC1 nanocomposite signifies that the composite has weak DNA binding activity. Antioxidant activity demonstrates that Ag/SC1 nanocomposite exhibits weak activity towards scavenging behavior of ABTS •+ and good anti-hemolytic activity of red blood cells comparing with ascorbic acid. The antimicrobial activity of Ag/SC1 nanocomposite against some bacterial strains offered better antibacterial properties than the nanosized SC1.

“…At regular time intervals, during the degradation process, the aliquot of each flask was withdrawn, and the absorbance was recorded at λ = 580 nm for MV2B dye. [33] The same procedures were used in control experiments in absence of a catalyst. Also, the catalytic activity of the catalyst SC in presence of different scavengers such as benzoquinone (BQ), ammonium oxalate (AO), and isopropyl alcohol (IPA) was carried out under the same conditions.…”

∞ 3 [{Co(hmt) 2 (NCS) 2 (H 2 O) 2 }{Co(NCS) 2 (H 2 O) 4 }(2H 2 O)] supramolecular complex (SC) had been synthesized through self-assembly reaction using the sonochemical method at ambient conditions. The structure was fully characterized by single-crystal X-ray diffraction and spectroscopic methods. The structure consists of two separate distinct complexes containing two crystallography and chemically different Co II atoms, four thiocyanate ligands, two hmt ligands, six coordinated water molecules, and one uncoordinated water molecule. The two Co II (SCN) 2 fragments adopt 1D chains which extend three dimensionally via strong H bonds. Radiation catalysis is a promising wastewater treatment method, which is used to remove dyes under UV and ultrasonic radiation in the presence of a heterogeneous catalyst. SC exhibits efficient heterogeneous catalysis for degradation of methyl violet 2B (MV2B) dye which was used as a model pollutant in presence of H 2 O 2 under ambient conditions. UV irradiation and ultrasonic irradiation reveal significant enhancement in degradation efficiency and time. The morphological features of SC are examined by transition electron microscopy (TEM) and scanning electron microscopy (SEM) before and after degradation.

The coordination polymer {[Cu6(CN)6]·HPD}n, CP1; (HPD = heptane‐1,7‐diamine) was prepared and characterized by single‐crystal and powder X‐ray diffraction, UV–Vis spectroscopy, electron microscopy (TEM and SEM), and elemental analyses. The copper atoms are coordinated by C ≡ N ligands, and both exhibit tetrahedral geometry. Cu1 and Cu2 create the pretty unique cluster structure of two quadruple [Cu2(μ3‐CN)2] units exhibiting coprophilic interaction. The building blocks [Cu3(CN)3]2 form fused distorted rectangular rings surrounded with the [Cu2(μ3‐CN)2] motifs exhibiting wide voids to accommodate the guest HPD. The structure of 1 indicates the formation of channels with dimensions 5.121–8.469 Ǻ which extend three‐dimensionally creating fused cavity morphology with different shapes. CP1 was utilized as an efficient sensor for selective quantitative estimation of metal ions (Co2+) and explosives (NB). Advanced oxidation process (AOP) was used as an efficient photocatalyst for the removal of the antibiotic meloxicam (MEL) utilizing AOP in the presence of H2O2 as an oxidant. Scavenge experiments, reusability of catalyst 1, and mechanism of oxidation were also discussed.
