New pyridine based ruthenium complexes with different substituents were synthesized and characterized by Uv-Visible, fluorescence, FTIR NMR spectroscopies. The solvent effects of the compounds on photoluminescence properties have been investigated. exhibit solvatochromic effect in solvents. electrochemical studies performed cyclic voltammetry. HOMO LUMO energy levels are range (-5.51)-(-5.52) e...
• Reacting Ru(CO) 4 Br 2 with heterocyclic amines leads to ruthenium carbamoyls. These complexes release CO only when irradiated in the UV. The metal coordination spheres are similar releated iron systems. Reaction of a series family carbamoyl complexes. analogous related ferracyclic systems reported by us as potential photo corm ( Chem. Commun. , 2020, 56 4300–4303). In contrast compounds, car...
Materials that are strong at progressively higher temperatures are sought for use in aircraft engines, in order that operating temperatures, and thereby efficiency and performance, can be increased. Intermetallic compounds with high melting temperatures have the promise of higher strength and elastic stiffness while hot, but in most cases they suffer from extreme brittleness at room temperature...
Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...
The abundant and inexpensive carbon monoxide (CO) is widely exploited as a C1 source for the synthesis of both fine bulk chemicals. In this context, photochemical carbonylation reactions have emerged powerful tool sustainable carbonyl-containing compounds (esters, amides, ketones, etc.). This review aims at giving general overview on visible light-promoted in presence metal (Palladium, Iridium,...

Ruthenium compounds have become promising alternatives to platinum drugs by displaying specific activities against different cancers and favourable toxicity and clearance properties. Nonetheless, their molecular targeting and mechanism of action are poorly understood. Here we study two prototypical ruthenium-arene agents-the cytotoxic antiprimary tumour compound [(η(6)-p-cymene)Ru(ethylene-diam...
