Direct C–H functionalization catalyzed by a robust and recyclable heterogeneous catalyst is highly desirable for sustainable fine chemical synthesis. Bipyridine units covalently incorporated into the backbone of porous organic polymer were used as macroligand heterogenization molecular nickel catalyst. A controlled loading within achieved, coordination to bipyridine (bpy) sites assessed at leve...

In the crystal structure of the title compound, [Cu(2)(N(3))(2)(C(10)H(8)N(2))](n), each Cu(I) atom is coordinated by two symmetry-related azide anions and 4,4'-bipyridine (bipy) ligands in a strongly distorted tetra-hedral geometry. The Cu atom and the azide anion occupy general positions while the bipy mol-ecule is located on a centre of inversion. Each two symmetry-related copper(I) cations ...

In the title complex mol-ecule, [CdBr(2)(C(10)H(8)N(2))(2)], the Cd(II) ion is six-coordinated by two cis-arranged bromide anions and four N atoms of two bidentate 2,2'-bipyridine ligands in a distorted octa-hedral geometry. The dihedral angle formed by the mean planes through the bipyridine ligands is 87.01 (11)°. In the crystal packing, π-π stacking inter-actions [centroid-centroid distances ...

Rh(III) and Ir(III) can be complexed to bipyridine groups attached to the termini of bis(dioxaborine)-capped heptamethines; these chromophores exhibit large third-order polarisabilities at 1.55 μm, while retaining good film-forming properties and linear optical transparency in the near infrared.

The title compound, [Ru(C(10)H(8)N(2))(2)(C(13)H(7)N(3)S)](PF(6))(2)·CH(3)CN, was synthesized by the reaction of thio-phosgene and bis-(2,2'-bipyridine)(1,10-phenanthrolin-5-amine)ruthenium(II) bis-(hexa-fluoridophosphate). The Ru(II) atom adopts a slightly distorted octa-hedral RuN(6) coordinaton formed by four N atoms of two bipyridine ligands and by two N atoms of the 1,10-phenantroline liga...

6-(1-Methylpyrrol-2-yl)-2,2'-bipyridine, 3, and 6-(selenophene-2-yl)-2,2'-bipyridine, 4, have been prepared and characterized in solution and by structural determinations. Copper(I) complexes [CuL(2)][PF(6)] in which L is 2,2'-bipyridine substituted in the 6-position by furyl, thienyl, N-methylpyrrolyl, selenopheneyl, methyl or phenyl, (L = 1-6) have been synthesized. The complexes have been ch...

The asymmetric unit of the title compound, 3C(10)H(8)N(2)·2C(7)H(7)NO(2), consists of three mol-ecules of 4,4'-bipyridine (bpy) and two mol-ecules of 3-amino-benzoic acid (bza). Two mol-ecules of bza and two mol-ecules of bpy are connected via O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds, forming forming infinite double-stranded zigzag chains along the c axis. The third mol-ecule of bpy is linked to t...

In the title 1:2 adduct, C(10)H(8)N(2)·2C(7)HF(5)O(2), the complete 4,4'-bipyridine mol-ecule is generated by a crystallographic twofold axis. The components of the adduct are linked by inter-molecular O-H⋯N hydrogen bonds and further connected by a combination of C-H⋯O, C-H⋯F and F⋯F [2.859 (2) Å] inter-actions.

Four iridium(III) dyes functionalized with aldehyde functional group in the cyclometalating (C^N) ligands, bearing either diethyl [2,2′-bipyridine]-4,4′-dicarboxylate or tetraethyl [2,2′-bipyridine]-4,4′-diylbis(phosphonate) anchoring groups, coded as Ir1–Ir4, are synthesized and explored photosensitizers. The synthetic route is described all of complexes characterized respect to their electroc...

In the title compound, [Cu(C(8)H(7)O(2))(NO(3))(C(10)H(8)N(2))], the Cu(II) ion is five-coordinate in a distorted square-pyramidal geometry. The basal positions are occupied by two N atoms from a 2,2'-bipyridine ligand and two O atoms from the 2-acetyl-phenolate anion. The axial position is occupied by one O atom of a nitrate anion. In the bipyridine ligand, the two pyridine rings are slightly ...
