We report the successful use of Ru(II)(terpy)(2) (1, terpy = 2,2':6',2''-terpyridine) as a catalyst in the Belousov-Zhabotinsky (BZ) oscillating chemical reaction. We also examine several additional Ru(II) complexes, Ru(II)(bipy)(2)(L')(2) (2, L' = 4-pyridinecarboxylic acid; bipy = 2,2'-bipyridine) and Ru(II)(bipy)(2)(L'') (3, L'' = 4,4'-dicarboxy-2,2'-bipy; 4, L'' = N-allyl-4'-methyl-[2,2'-bip...

In the structure of the title compound, 2[Ag(C(10)H(8)N(2))(H(2)O)](C(7)H(6)NO(2))(NO(3))·H(2)O, the Ag(I) atom is three-coordinated in a T-shaped configuration by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) ligands at short distances and by one water O atom at a longer distance. Each bipy ligand bridges two neighbouring Ag(I) atoms, forming a chain structure extending parallel...

The hydrophilic, long-chain diamine PEGda (O,O'-bis(2-aminoethyl)octadeca(ethylene glycol)), when complexed with cis-protected Pt(II) ions afforded water-soluble complexes of the type [Pt(N,N)(PEGda)](NO(3))(2) (N,N = N,N,N',N'-tetramethyl-1,2-diaminoethane (tmeda), 1,2-diaminoethane (en), and 2,2'-bipyridine (2,2'-bipy)) featuring unusual 62-membered chelate rings. Equimolar mixtures containin...

Five novel coordination polymers [Zn(2)(OA)(4,4'-bipy)(H(2)O)].0.5(4,4'-bipy), [Zn(2)(OA)(dib)(H(2)O)].H(2)O, [Zn(2)(OA)(bbi)(2)].3H(2)O, [Zn(2)(OA)(phen)(2)(H(2)O)] and [Zn(4)(OA)(2)(2,2'-bipy)(2)(H(2)O)].2H(2)O were obtained by hydrothermal reactions of Zn(NO(3))(2).6H(2)O with a V-shaped multicarboxylate ligand 3,3',4,4'-oxydiphthalic acid (H(4)OA) and a series of N-donor ligands, namely 4,4...

Triple-negative breast cancer (TNBC) is a highly aggressive breast cancer subtype. The high rate of metastasis associated to the fact that these cells frequently display multidrug resistance, make the treatment of metastatic disease difficult. Development of antitumor metal-based drugs was started with the discovery of cisplatin, however, the severe side effects represent a limitation for its c...

The reduction and subsequent reactions of the series of mixed ligand cobalt() complex cations, [Co(bipy)3] 3 , [Co(phen)3] 3 , [Co(en)3] 3 , [Co(en)2(bipy)] 3 , [Co(en)2(phen)] 3 , [Co(en)2(5-NO2-phen)] 3 , [Co(en)2(DPPZ)] 3 , [Co(bipy)2(NH3)2] 3 , [Co(bipy)(NH3)4] 3 , [Co(phen)2(NH3)2](ClO4)3] 3 and [Co(phen)(NH3)4] 3 , (where bipy is 2,2 -bipyridine, phen is 1,10-phenanthroline, en is ethy...

Both manganese and rhenium complexes of the type [M(bipy)(CO)(3)(N-RIm)](+) (bipy=2,2'-bipyridine) undergo deprotonation of the central CH group of the N-alkylimidazole (N-RIm) ligand when treated with a strong base. However, the outcome of the reaction is very different for either metal. For Mn, the addition of the equimolar amount of an acid to the product of the deprotonation affords an N-he...

The present study describes the synthesis, characterization, antileishmanial and antiplasmodial activities of novel diimine/(2,2'-bipyridine (bipy), 1,10-phenanthroline (phen), 4,4'-methylbipyridine (Me-bipy) and 4,4'-methoxybipyridine (MeO-bipy)/phosphine/ruthenium(II) complexes containing lapachol (Lap, 2-hydroxy-3-(3-33 methyl-2-buthenyl)-1,4-naphthoquinone) as bidentate ligand. The [Ru(Lap)...

Single-crystal X-ray structure determinations are reported for four lanthanide complexes, [Dy(bipy)2Cl2(OH2)2]Cl.H2O (bipy = 2,2?-bipyridine), 1; [La2(phen)2(O2CCH3)4(NO3)2] (phen 1,10-phenanthroline), 2; [Lu(terpy)(O2CCH3)3].NaNO3 (terpy 2,2?;6?,2?-terpyridine) 3; and [Lu(phen)(O2CH)3(OH2)].H2O, 4. Dispersion interactions within the stacked arrays of coordinated aza-aromatic units found in all...
