    (2015) Matsinha, Leah Charlie; Smith, Gregory S; Mapolie, Selwyn F; Venter, Gerhard A
    The synthesis and characterization of monomeric and dimeric salicylaldimine water-soluble ligands is discussed. The salicylaldimine ligands (2.3-2.10) were synthesised via Schiff base condensation reactions of various amines with water-soluble sulfonated salicylaldehydes (2.1 and 2.2). The ligands were characterized using various analytical and spectroscopic techniques. Complexation reactions of these water-soluble ligands (2.3-2.10) with [Rh(COD)Cl]2 gave the corresponding water-soluble mononuclear (2.11-2.14) and binuclear (2.15-2.18) Rh(I) complexes. All the complexes were characterized using nuclear magnetic resonance spectroscopy, infrared spectroscopy, single crystal X-ray diffraction (for complex 2.14), mass spectrometry, elemental analysis and melting point determinations.
