Sažetak
The reactions of N-arylalkyl derivatives of iminodiacetic acid (BnidaH2, PpidaH2 and NO2- BnidaH2 ; Bn = benzyl, Pp = 3-phenylprop-1-yl and NO2-Bn = p-nitrobenzyl) with nickel(II) chloride hexahydrate or nickel(II) acetate tetrahydrate were studied in aqueous solutions. Four nickel(II) complexes [Ni(Bnida)(H2O)3] ∙ H2O (1), [Ni(Ppida) (H2O)3] ∙ H2O (2a), [Ni(Ppida)(H2O)3] (2b) and [Ni(NO2-Bnida)(H2O)3] ∙ ½H2O (3) were prepared and characterized by infrared spectroscopy and thermal analysis (TGA-DTA). The crystal structures of 1, 2b and 3 were determined by single-crystal X-ray structural analysis. The octahedral coordination environment around the nickel(II) ion in all of the prepared complexes consists of an O, N, O'- tridentate N-arylalkyliminodiacetate ion and three water molecules arranged in a fac-position. The molecules in the crystal structures of these complexes are connected into a complicated 2D hydrogen-bonded network, dominated by the O–H...O hydrogen bonds.
