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 1 H 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 C 2/ c with the two enantiomers in the unit cell. The emission spectrum of 4 exhibited the new compound as a green emitting complex.
