Copper(II) complexes of thioarylazo-pentanedione: Structures, magnetism, redox properties and correlation with DFT calculations
摘要:
Copper(II) complexes of 3-((2-(alkylthio)phenylazo)-2 4-pent inedione tridentate O N S donor ligands are described in this work Chloride bridged copper(II) polymers (1) and thiocyanato bridged copper(II) dimmers (2) are characterized by a single crystal X-ray diffraction study The complexes show antiferromagnetic interactions with J = -0 5 +/- 0 1 cm(-1) (1a) and -25 8 +/- 0 5 cm(-1) (2b) which implies stronger coupling in the -SCN-bridging compound The spectra redox and magnetism are explained by DFT studies (C) 2010 Elsevier Ltd All rights reserved
