چکیده
Thermal activation of terpyridine in the presence of an unsaturated Ir(III) fragment stabilized by a hydrotris(pyrazolyl) borate ligand gives rise to mononuclear complex and binuclear , in which the polypyridine behaves, respectively, as a mono- or a bi-dentate N-heterocyclic carbene.

Unsaturated [Tp(Me2)Ir(III)] fragments, readily generated from compounds [Tp(Me2)Ir(C(6)H(5))(2)(N(2))], (1a) and [Tp(Me2)Ir(η(4)-CH(2)=C(Me)C(Me)=CH(2)] (1b) (Tp(Me2) = hydrotris(3,5-dimethylpyrazolyl)borate), induce the isomerisation of the polypyridines, 2,2'-bipyridine, 1,10-phenanthroline and 2,2':6'2''-terpyridine, to form complexes that contain the carbene tautomer of these ligands. For ...

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 title compound, {[NdPt(CN)(4)(NO(3))(C(15)H(11)N(3))(H(2)O)(2)]·CH(3)CN·0.5C(15)H(11)N(3)}(n), was isolated from solution as a one-dimensional coordination polymer. The Nd(3+) site in the structure has a ninefold coordination with a distorted tricapped trigonal-prismatic geometry, while the Pt(II) ion is coordinated by four cyanide groups in an almost regular square-planar geometry. Cis-bri...
