Six homologous gold(III) dinuclear oxo-bridged complexes, of the type [(bipy)Au(μ-O)2Au(bipy)][PF6]2, bearing variously substituted 2,2’-bipyridine ligands (bipy = 2,2’-bipyridine, 4,4’-di-tert-butyl-, 6-methyl-, 6-neopentyl-, 6-o-xylyland 6,6’-dimethyl-2,2’-bipyridine), here called Auoxos, were prepared, characterised and recently tested as potential anticancer agents. Crystal structures were ...

In the title compound, [In(C(11)H(10)N(2))Cl(3)(C(2)H(6)OS)], the In(III) cation is six-coordinated in a distorted octa-hedral configuration by two N atoms from the chelating 6-methyl-2,2'-bipyridine ligand, one O atom from a dimethyl-sulfoxide group and three Cl(-) anions. Weak inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds and intra-molecular C-H⋯Cl hydrogen bonds are present in the structure.

We report the synthesis and the photophysical properties of UV light-harvesting arrays constructed around a [Ru(bpy)3] core (bpy ) 2,2′-bipyridine) bearing one and three pyrenyl units in the periphery. The free ligand containing the pyrenyl unit, 4-methyl-4′-(2-hydroxyethylpyrenyl)-2,2′-bipyridine, displays an intense emission band centered near 400 nm with a lifetime of 264 ns, characteristic ...

• The salts with protonated bipyridines and [W(CN) 6 (bpy)] 2- were synthesized. layered structure of compared to their analogues alkali metal cations. dimethyl substituted bipyridine as a cation shows 3D dimensionality. cation-anion distance was discussed in relation position the UV-Vis bands. ion-pair-charge-transfer transitions these found 8 ] 4− analogues. series 2− 2,2′-bpy (1), 4,4′-bpy (...

Photophysical properties of the salts [Ru(bpy)(3)](p-Tos)(2), [Ru(dmb)(3)](PF(6))(2), [Ru(vbpy)(3)](PF(6))(2), and [Ru(phen)(3)](p-Tos)(2) (bpy = 2,2'-bipyridine, dmb = 4,4'-dimethyl-2,2'-bipyridine, vbpy = 4-methyl-4'-vinyl-2,2'-bipyridine, phen = 1,10-phenanthroline, and p-Tos = p-toluene sulfonate) in fluid and film polyethylene glycol dimethacrylate containing nine ethylene glycol spacers (...

The asymmetric unit of the title complex, [Pt(CH(3))(3)(C(10)H(8)N(2))(C(4)H(7)NS(2))]BF(4), contains two crystallographically independent mol-ecules. The Pt(IV) atom in each complex cation exhibits a distorted octa-hedral coordination geometry, built up by three methyl ligands in a facial binding fashion, a bipyridine ligand and a monodentately N-bound 2-methyl-sulfanyl-2-thia-zoline ligand (c...

In the title compound, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))], the Pb(II) ion is coordinated by two N atoms from one 2,2'-bipyridine ligand and four O atoms from two 4-methyl-benzoate anions in a distorted pseudo-square-pyramidal environment, considering one of the carboxyl-ate anions as an apical ligand. Pairs of complex mol-ecules related by inversion centers are organized into dimers via pairs...

In the centrosymmetric trinuclear Zn(II)⋯Ca(II)⋯Zn(II) title complex, [CaZn2(CH3COO)6(C12H12N2)2], the Ca(II) ion lies on an inversion centre and is octa-hedrally coordinated by six acetate O atoms. The Zn(II) ion is coordinated by two N atoms from a bidentate di-methyl-bipyridine ligand and three O atoms from acetate ligands bridging to the Ca(II) ion, leading to a distorted square-pyramidal c...
