Copper coordination compounds with (5Z,5Z′)-2,2′-(alkane-α,ω-diyldiselenyl)-bis-5-(2-pyridylmethylene)-3,5-dihydro-4H-imidazol-4-ones. Comparison with sulfur analogue

Abstract

Mono- and binuclear Cu(+1/+2) complexes of bis-5-(2-pyridyimethylene)-2-selenohydantoins were obtained by the reactions of corresponding ligands with copper(+2) chloride or perchlorate in BuOH/DCM mixtures.

(4Z,4′Z)-2,2′-(Ethane-1,2-diylbis(sulfanediyl))bis(1-phenyl)-4-(pyridin-2-ylmethylene)-1H-imidazol-5(4H)-one)dicopper(II) Tetrabromide

“…The electronic characteristics of the organic ligand (such as donor/acceptor substituents) determine its oxidation potential and complexation with copper ions. In previous work, we synthesized a series of 3-aryl-substituted 2-thioxoimidazole-4-ones and binuclear coordination compounds based on Cu (II) dichloride [9,10]. We were interested in the molecular structure of this chemical class.…”
