• Nickel(II) complexes
• Iminodiacetate
• Imidazole
• Crystal structure

In an attempt to prepare binary and ternary compounds, we have obtained two molecular complexes [Ni(MEBIDA or MOBIDA)(H(2)O)(3)]center dot nH(2)O (n = 0 or 1) and two iso-type salts [Ni(Him)(6)][Ni(MEBIDA or MOBIDA)(2)]center dot 4H(2)O [MEBIDA = N-(p-methylbenzyl)iminodiacetate(2-) and MOBIDA = N-(p-methoxybenzyl)iminodiacetate(2-) ligands, Him = imidazole]. Our results are discussed with regard to related copper(II) and nickel(II) compounds. The reasons for which these chelating ligands produce nickel(II) salts instead of ternary compounds remain unclear since other iminodiacetate-like ligands give true ternary Ni(II) compounds with imidazole and other N-heterocyclic ligands.
