A new series of N-Heterocyclic carbene based ligands and their silver(I) complexes was obtained and tested in vitro on three bacterial strains (Bacillus subtillis, Bacillus cereus and Macrococcus brunensis) to assess their antibacterial potential. Hemolytic and thrombolytic activities of ligands and complexes on normal mouse erythrocytes were also assessed. In vitro antibacterial study of ligands...

It contains two dimensional (2D) planar grid networks with the Schläfli symbol (4 4 ) stacked in a stagger-peaked fashion. This CdL was fabricated into humidity sensor and the...

The structure of 1 manifests a three-fold interpenetrated 3D pcu topology based on paddle-wheel...
The solvothermal reactions of 5,5′-(4,4′-phenylene-bis-(methyleneoxy)) diisophthalic acid (H 4 L) and two chelating N-donor ancillary ligands with Co(II) yielded two new metal–organic frameworks (MOFs) viz., [Co 2 (μ 2 -H 2 O)(L)(2,2′-bipy) 2 ] n (1) and [Co 2 (μ 2 -H 2 O)(L)(phen) 2 ] n (2) (2,2′-bipy = 2,2′-bipyridine and phen = 1,10-phenanthroline). The single-crystal X-ray diffraction studies...
Low dimensional organic-inorganic hybrid Bi(III) halides, especially those containing organic N, S-heterocycles are amazing as solid state photoluminescent materials, but remain less explored. Herein, two bismuth(III) halide compounds, (Etmp) 4 Bi 2 X 10 (X = Cl for 1, Br for 2, Etmp = 4-(ethylthio)pyridin-1-ium), are obtained by employing pyridyl sulfide derivative as counter cations. They are determined...
The carbon/BiOI composite photocatalysts were synthesis by hydrothermal reaction and characterized by various methods. The as-prepared photocatalysts were used to remove organic pollutants in aqueous solution under visible light irradiation. The C/BiOI samples demonstrated excellent photocatalytic performance for degradation of methyl orange (MO), which is about 4 times higher than that of BiOI. Furthermore,...
Three iridium(III) complexes [Ir(ppy) 2 (DQPC)](PF 6 ) (Ir-1), [Ir(bzq) 2 (DQPC)](PF 6 ) (Ir-2) and [Ir(piq) 2 (DQPC)](PF 6 ) (Ir-3) were synthesized and characterized. The cytotoxicity in vitro of the ligand DQPC and complexes Ir-1, Ir-2 and Ir-3 against cancer cells HeLa, A549, HepG2 and normal cell NIH3T3 was assessed by MTT methods. These complexes exhibit significant inhibitory effect on HeLa...
Benzimidazoline-2-ylidene complexes of palladium(II) were synthesized mechanochemically in a vibratory ball mill. Complete syntheses began with preparation of benzimidiazolium halides from commercially available starting materials. These “greener chemistry” syntheses proceed in high yield and require minimal purification using environmentally benign solvents. Kinetic analysis shows that liquid assisted...

Chemical bath deposition (CBD) route was used to prepared lead sulphide (PbS) thin films on glass substrates by using triethylamin (Et 3 N) as complexing agent. The influence of varying the concentration of Et 3 N on the electrical, morphological, photoluminescence and structural properties of the deposited thin films were studied.
