The first syntheses of monomeric and oligomeric aziridine complexes of copper(I) are described. Cu(I)Br (1) reacts with a series of different aziridine derivatives (C2H3PhNH (2), C2H 2Me2NH (3), C2H2Me 2NC2H2Me2NH2 (4)) to give the neutral dimeric complex [CuBr(C2H3PhNH) 2]2 (5) and the ionic hexameric complex [Cu 6Br5(C2H2Me2NH) 6]Br (6) with terminal bound aziridine ligands as well as the neutral monomeric complex [CuBr(C2H2Me2NC 2H2Me2NH2)] (7) where the dimerized aziridine acts as a N,N′-chelating ligand. After purification, all of the complexes were fully characterized and their IR, 1H and 13C NMR spectra are reported and discussed. The single crystal structure analysis revealed distorted tetrahedral geometry for the copper(i) centres in the complexes 5 and 6 and a trigonal planar structure for complex 7. In the oligomers the copper centres are bridged by two μ2- (5) or two μ3- and three μ4-bromido ligands (6), respectively. The Royal Society of Chemistry 2010.
