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...

Seven new hetero triply-bridged dinuclear Cu(II) compounds have been synthesized and characterized corresponding to a series with general formula [Cu(2)(L)(2)(μ-OH)(μ-OH(2))(μ-O(2)CR)]X(2) (where L = bpy = 2,2'-bipyridine, 4,4'-dmbpy = 4,4'-dimethyl-2,2'-bipyridine and 5,5'-dmbpy = 5,5'-dimethyl-2,2'-bipyridine; R = H for formate, CH(3) for acetate, CH(2)CH(3) for propionate and C(CH(3))(3) for...

In the title compound, C(10)H(8)N(2)·C(4)H(8)N(2)O(2), both the dimethyl-glyoxime and the 4,4'-bipyridine mol-ecules have crystallographic C(i) symmetry. The mol-ecules stack along the a-axis direction with a dihedral angle of 20.4 (8)° between their planes. In the crystal, the components are linked by O-H⋯N hydrogen bonds into alternating chains along [120] and [1[Formula: see text]0].

The electrochemical reduction of allyl chloride is strongly catalyzed in the presence of cobalt complexes of 2,2'-bipyridine. A prominent reaction product of the catalyzed reduction is 1,5-hexadiene. Voltammetry, coulometry, and gas chromatographic data are presented and analyzed and a mechanistic scheme proposed to. account for the catalytic action of the cobalt-2,2'-bipyridine complexes. Rece...

Heterotetrametallic [{[Ti](μ-σ,π-C≡CSiMe3)2}Cu-bipy-C≡C-AuPh2PFc]PF6 (5) ([Ti] = (ηC5H4SiMe3)2Ti; Fc = (η-C5H4)(η-C5H5)Fe; bipy = 2,2`-bipyridine) is accessible by the consecutive reaction of FcPPh2-AuCl (1) with 5-ethynyl-2,2`-bipyridine (2) producing FcPPh2-AuC≡C-bipy (3) which further reacts with [{[Ti](μ-σ,π-C≡CSiMe3)2}Cu(N≡CMe)]PF6 (4) to give the title complex in which four different tran...

A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu(2+) with a 1:1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials ...

The crystal structure of the title complex, [Ni(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n), exhibits a two-dimensional network, which is built up from slightly distorted NiN(4)O(2) polyhedra (2 symmetry), bipyridine ligands, and carboxyl-ate anions. The Ni(II) atoms are six-coordinated by two O atoms of two monodentate carboxyl-ate anions and four N atoms from bipyridine ligands and are connected ...
