The insertion of ruthenium(II) into an azuliporphyrin (TPAP) has yielded carbonyl ruthenium(II) azuliporphyrin [Ru(TPAP)(CO)] featuring an equatorial CNNN set of donors. Its azulene moiety serves as the π-coordination platform to accommodate the Ru4(CO)9 cluster. This chemistry proved to be general giving rise to a series of bimetallic complexes [M(TPAP){Ru4(CO)9}] (M = Ru(CO), Ni, Pd, Pt).

Ruthenium complexes have been considered as promising substitutes for cisplatin in cancer chemotherapy. However, novel ruthenium-based therapies are faced with some limitations, such as unimpressive cytotoxicity toward solid tumors. Herein, we designed and synthesized phenyl-substituted terpyridyl ruthenium(ii) complexes ([Ru(tpy)(bpy)Cl](+) (Ru1), [Ru(phtpy)(bpy)Cl](+) (Ru2) and [Ru(biphtpy)(b...

Heterogeneous catalysts of ruthenium were prepared by impregnation on activated carbon and ZSM-5 and were used to degrade phenol in the presence of peroxymonosulphate (PMS). The ruthenium based catalysts were characterised by several techniques such as XRD, SEM, and N2 adsorption. It was found that Ru-AC is highly effective in heterogeneous activation of peroxymonosulphate to produce sulphate r...

The catalytic activity of ruthenium(II) bis(diimine) complexes cis-[Ru(6,6′-Cl2bpy)2(OH2)2](Z)2 (1, Z=CF3SO3; 2, Z= (3,5-(CF3)2C6H3)4B, i.e. BArF) and cis-[Ru(4,4′-Cl2bpy)2(OH2)2](Z)2 (3, Z=CF3SO3; 4, Z=BArF) for the hydrogenation and/or the hydrogenolysis of furfural (FFR) and furfuryl alcohol (FFA) was investigated. Themolecular structures of cis-[Ru(4,4′-Cl2bpy)2(CH3CN)2](CF3SO3)2 (3′) and d...

In the current work, we present use of two free-base and zinc-metallated porphyrin-ruthenium(II) polypyridine dyads, along with reference porphyrin derivatives, as sensitizers in both n- p-type DSSCs DSPECs. Two dyads contain well-known Ru(bpy)3 unit (HOOC-DMP-Ru(bpy)3 HOOC-(Zn)DMP-Ru(bpy)3), while other terpyridine-Ru(Cl)-bypiridine was used (HOOC-DMP-tpy-Ru HOOC-(Zn)DMP-tpy-Ru). all systems, ...

A new ligand bearing two tpy moieties and one bpy unit (tpy = 2,2':6',2''-terpyridine; bpy = 2,2'-bipyridine) linked by carbon-carbon single bonds and its corresponding trinuclear ruthenium complex were readily synthesized in high yield, and characterized by (1)H NMR spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESI/MS) and elemental analysis. The ruthenium complex...

The mechanism by which the most relevant ruthenium anticancer drugs are activated in tumors to commence their tumor-inhibiting action remains one of the challenging research tasks of present-day metallomics. This contribution aims to capture and identify eventually more reactive species of one of two bis-indazole tetrachloridoruthenate(III) compounds that are progressing in clinical trials. In ...

taining polyaminocarboxylate (pac) ligands (Ru-pac) is of continuing interest. The donor character of the pac ligand is comparable with that of many biological enzymes which make use of the carboxylate and amine donors from amino acids to bind to a metal centre. The pac ligand can form very stable 1:1 (metal : ligand) complexes with ruthenium. Early studies (1-3), later confirmed by crystallogr...
