Preparation and NMR spectroscopic study of palladium(II) complexes with N-arylalkyliminodiacetamide derivatives

The reactions of N-arylalkyl derivatives of iminodiacetamide, RN(CH2CONH2)2 ; Rimda (Bnimda, Peimda, Ppimda, o-ClBnimda, p-ClBnimda ; Bn = benzyl, Pe = 2-phenylethyl ; Pp = 3-phenylprop-1-yl ; o-ClBn = o-chlorobenzyl ; p-ClBn = p-chlorobenzyl) with palladium(II) chloride in acidic aqueous solutions were investigated. Six new palladium(II) complexes, belonging to three different types, namely [PdCl2(Bnimda)]2 · 2H2O (1 ; type I), [PdCl2(Peimda)] · H2O (2 ; type II), [PdCl2(Ppimda)] · ½H2O (3a ; type II), [PdCl2(Ppimda)]2 (3b ; type I), [PdCl2(p-ClBnimda)] · H2O (4 ; type II) and [PdCl2(o-ClBnimda)2] (5 ; type III) were obtained and characterized by infrared spectroscopy, 1H and 13C NMR spectroscopy, and thermal analysis (TG/DTA).
