The title compound, C(20)H(22)N(6) (2+)·2PF(6) (-), was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with 1-methyl-imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one hexa-fluoro-phosphate anion. The dihedral angle between the p...

A new binuclear complex of [{NiCl(6-mbipy)}2(μ-Cl)2] (1) was prepared from the reaction of NiCl2.6H2O and 6-methyl-2,2'-bipyridine (6-mbipy)  in a mixture of methanol and acetonitrile. Suitable crystals of 1 for X-ray diffraction measurement were obtained by slow evaporation of the resulted green solution at room ...

The synthesis and characterization of eight new bis-cyclometalated compounds [M(ptpy)2(N^N)]PF6 (ptpy=2-(p-tolyl)pyridinato; N^N=5-chloro-1,10-phenanthroline: M=Rh, 1; M=Ir, 2); N^N=5-methyl-1,10-phenanthroline: 3; 4; N^N=4,4’-diphenyl-2,2’-bipyridine: 5; 6; N^N=4,4’-diamino-2,2’-bipyridine: 7; 8) are described. All were characterized by spectroscopic means. Additionally, the molecular structur...

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...
