Abstract: | Complexes of N-phthaloylglycinate (N-phthgly) and CoII, NiII, CuII, ZnII and CdII containing imidazole (imi), N-methylimidazole (mimi), 2,2-bipyridyl (bipy) and 1,10-phenanthroline (phen), and tridentate amines such as 2,2,2-terpyridine (terpy) and 2,4,6-(2-pyridyl)s-triazine (tptz), were prepared and characterized by conventional methods, i.r. spectra and by thermogravimetric analysis. For imi and mimi ternary complexes, the general formula M(imi/mimi)2(N-phthgly)2]·nH2O, where M = CoII, NiII, CuII and ZnII applies. For CdII ternary complexes with imi, Cd(imi)3(N-phthgly)2]·2H2O applies. For the bi and tridentate ligands, ternary complexes of the formula M(L)(N-phthgly)2]·nH2O were obtained, where M = CoII, NiII, CuII and ZnII; L = bipy, phen, tptz and terpy. In all complexes, N-phthgly acts as a monodentate ligand, coordinating metal ions through the carboxylate oxygen, except for the ternary complexes of CoII, NiII and CuII with mimi and CuII and ZnII with imi, where the N-phthgly acts as a bidentate ligand, coordinating the metal ions through both carboxylate oxygen atoms. |
