Abstract

The cyclic structure of 2-phenyl-2-(2-pyridyl)imidazolidine (1) derived from the condensation of 1,2-diaminoethane and 2-benzoylpyridine has been confirmed by X-ray crystallography. Reaction of (1) with salts of nickel(II) and copper(II) leads to metal induced ring opening and the formation of complexes containing the tridentate ligand (L). The formulae of the complexes derived from NiX₂ and CuX₂ are [NiL₂]X₂ and [CuLY]X₂ (X=ClO₄^-, Y = H₂O, CH₃CN and N₃^-). Crystal structures were obtained for (1), [NiL₂][ClO₄]₂, [CuL(CH₃CN)][ClO₄]₂, [CuL(H₂O)][NO₃]₂ and [CuLN₃][ClO₄].
