Popis:	Reaction of 1-(4-picolyl)pyrrolidin-2-one (ppo) with hydrated copper(II) chloride or bromide in methanol affords the compounds [Cu(ppo)2X2](X = Cl or Br). A single-crystal X-ray diffraction study of [Cu(ppo)2Br2]1 shows that the ppo molecule acts as a bridging ligand with the formation of all trans-CuBr2N2O2 units linked to produce sheets of contiguous 36-membered rings. The EPR spectra of 1 and its chloride analogue give well resolved rhombic-type spectra. The EPR and electronic spectra of [Cu(ppo)2X2](X = Cl or Br) are analysed in terms of angular-overlap bonding parameters. X-Ray studies show that the compound [Cu4OCl6(ppo)4] comprises a Cu4(µ4-O)Cl6 core with an N-bonded ppo ligand co-ordinated to each Cu atom.
