 Title    Preparation and Properties of Rhodium(III) Complexes with the T etr adentate Ligand N,N'-Bis(2'-py ridi neearbox am ide)-1,8-naphthalene  
 Abstract    Synthetic procedures are described that allow access to a number of new Rh(III) complexes with the tetradentate bis-amide ligand N,N'-bis(2'-pyridinecarboxamide)-1,8-naphthalene (LH2). These complexes have the formulae Rh(LH2)Cl3, Na[RhLX2] • H20 (X = Cl, CN) and [RhLA2]C104 (A = pyridine, 1-methylbenzotriazole). The compounds have been characterized by elemental analyses, conductivity measurements, X-ray powder patterns, spectroscopic (IR, UV/VIS, 'H NMR) studies and electrochemical methods. The neutral amide behaves as a bis-bidentate ligand in the oligomeric or polymeric, octahedral complex Rh(LH,)Cl3. Monomeric, trans octahedral structures are assigned for the complexes o f L2" in the solid state; the doubly deprotonated ligand acts as a tetradentate chelating agent with the four nitrogens as ligating atoms.
