Metal complexes of aromatic amine n-oxides

6,6′-bis-(5,6-diethyl-[1,2,4]triazin-3-yl)-2,2′-bipyridyl the first example of a new class of quadridentate heterocyclic extraction reagents for the separation of americium(III) and europium(III)

The coordination chemistry of aromatic amine N-oxides

Six new lead coordination polymers, namely, [Pb(INO)2]·3H2O (1), [Pb(INO)2·NO3·H2O] (2), [Pb(INO)·Cl] (3), Na1.5[Pb2(INO)5]·0.5NO3 (4), [Pb3(NNO)4·(NO3)2·H2O] (5), and [Pb(NNO)2] (6), have been prepared by the reaction of Pb(NO3)2 with isonicotinic acid N-oxide (HINO), or nicotinic acid N-oxide (HNNO), and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. Compound 1, consisting of a one-dimensional (1D) infinite chain, is a three-dimensional (3D) supramolecular framework with a 1D rectanglar channel in which free water molecules locate. The structure of 2 consists of 1D chains built by two parallel INO ligands bridging a pair of rhombic-planar [Pb2O2] units, which is further extended into a 2D supramolecular layer via hypervalent interactions and interlayer π-π interactions. Compound 3 consists of a two-dimensional (2D) inorganic layer containing 16-membered rings, which are further linked through μ-INO to generate a unique 3D open framework. In compound 4, the self-assembly b...
