Synthesis of the tris-chelated complexes [Ru(L) n (L 3 ) 3−n ] 2+ (L= N-aryl-pyridine-2-aldimine, L 3 = 2-(m-tolylazo)pyridine) based on silver(I) assisted trans-metallation is described. The complexes, [Ru(L) 3 ] 2+ and [Ru(L)(L 3 ) 2 ] 2+ afford [Ru(pic)(L) 2 ] + and [Ru(pic)(L 3 ) 2 ]...
Three geometric isomers of [RuCl 2 L 2 ](ClO 4 ) (L = N-phenyl-2-pyridine carboxaldimine) have been isolated by stereoretentive oxidation of the corresponding isomeric ruthenium(II) complexes using Cl 2 (g) as an oxidant, followed by the addition of aqueous sodium perchlorate. These complexes are paramagnetic (low-spin d 5 , S = 1) and display rhombic EPR spectra...
