Abstract in another language

The synthesis and characterization of mononuclear tetrakis-aziridine nickel(II) and copper(II) complexes as well as of a dinuclear bis-aziridine copper(II) complex are described. The reactions of anhydrous MCl2 (M = NiII, CuII) with aziridine (= az = C2H4NH, C2H3MeNH, CH2CMe2NH) in CH2Cl2 at room temperature in a 1:5 and 1:2 molar ratio, respectively, afforded the tetrakis-aziridine complexes [M(az)4Cl2] (M = Ni, Cu) or the dimeric bis-aziridine complex [Cu(az)2Cl2]2. After purification, all of the complexes were fully characterized. The single crystal structure analysis revealed two different coordination modes. Whereas both nickel(II) complexes can be classified as showing an elongated octahedral structure, copper(II) complexes show either an elongated octahedral or a square pyramidal arrangement forming dimers with chlorido bridges in axial positions. Furthermore, the results of magnetic measurements of the nickel(II) and copper(II) compounds are presented.
