Azido-copper(II) and -copper(I) complexes of 1-alkyl-2-[(o-thioalkyl) phenylazo]imidazole (SRaaiNR') have been prepared and studied. Complex 2 [Cu(SRaaiNR')(μ1.1-N3)(N3)]2 dimerises via end-to-end (μ1,3)-N3 to form a tetrameric structure. Azido-copper(I) complexes of the ligands are obtained as MeOH-bridged dimers, [Cu(SRaaiNR')(N3)(μ-OHMe)]2 (3). The electronic spectra suggest that a small reorganisation energy (0.08 eV) is associated with the change in electronic configuration, structure and oxidation state from Cu11 to Cu1. Redox interconversion., Cu 11 Cu1, [Cu.(SMeaai.NMe)(μ-N3)(N 3)]2 (2a) ? [Cu(SMeaaiNMe)(N3)(μ- OHCH3)]2 (3a), has been performed in one case. The tetranuclear complex shows ferromagnetic and antiferromagnetic interactions. The spectra, redox chemistry and magnetism, are explained by DFT studies.
