  Mixed-ligand thiosemicarbazone complexes of nickel: Synthesis, structure and catalytic activity

  摘要：

  Reaction of thiosemicarbazones of salicylaldehyde, 2-hydroxyacetophenone and 2-hydroxynaphthaldehyde with Ni(ClO4)(2)center dot 6H(2)O, using 2,2'-bipyridine as coligand, afforded three dinuclear complexes (1a, 1b and 1c). Similar reactions using 2,2':6'2 ''-terpyridine as coligand yielded three mononuclear complexes (2a, 2b and 2c). Crystal structures of 1b and 2a have been determined. In the dinuclear complexes, one nickel center is surrounded octahedrally by a dianionic O,N,S-donor thiosemicarbazone, a bipyridine and the bridging phenolate oxygen of the other thiosemicarbazone. The second nickel center adopts a square-planar geometry created by the second O, N, S-coordinated thiosemicarbazone and the bridging sulfur of the first thiosemicarbazone. In the mononuclear complexes nickel is complexed by a monoanionic O, N, S-coordinated thiosemicarbazone and a terpyridine, and the cationic species are isolated as perchlorate salts. All these six complexes are paramagnetic (mu(eff) = 2.63-2.92 B. M.) and in dimethylsulfoxide solution they show intense absorptions in the visible and ultraviolet region, origin of which has been probed through DFT calculations. Cyclic voltammetry on the complexes shows one irreversible oxidation of coordinated thiosemicarbazone on the positive side of SCE, and one irreversible reduction of the coordinated polypyridine ligand on the negative side. These nickel complexes are found to be efficient catalysts for Suzuki cross-coupling reactions. (C) 2011 Elsevier B. V. All rights reserved.
