摘要

Reactions of complexes [{M(μ-Cl)(ptpy)_2}_2] (M = Rh, 1; M = Ir, 2; ptpy = 2-(p-tolyl)pyridinato) with glycinamide hydrochloride in methanol/dichloromethane in the presence of sodium methylate as the base were investigated. Thus, the new complexes [M(glycinamidato-N,N′)(ptpy) _2] (M = Rh, 3; M = Ir, 4) were obtained. The new chiral compounds were characterized by 2D~1H and ~(13)C NMR spectroscopic studies. The molecular structure of compound 4 was confirmed by X-ray diffraction. Complex 4 crystallized from dichloromethane/methanol/isohexane in the centrosymmetric space group C2/c with the two enantiomers in the unit cell. The emission spectrum of 4 exhibited the new compound as a green emitting complex.
