AbstractThe employment of a tridentate Schiff base ligand, 1-(((2-hydroxy-2,3-dihydro-1H-inden-1-yl)imino) methyl)naphthalen-2-ol (H2L) in the coordination chemistry of cobalt(II) acetate and copper(II) acetate is reported. One cubane-like cluster of formula [Co4L4].CH3OH (1.CH3OH) and one alkoxo-bridged dinuclear copper compound of composition [Cu2L2] (2) were achieved by the reactions of metal acetates with H2L under solvothermal conditions. The structures of 1.CH3OH and 2 have been established by single crystal X-ray diffraction studies. Complex 1"CH3OH has a cubane-like (Co4O4) core with divalent metal atoms and alkoxo atoms (originated from the L2- ligands) occupying alternating vertices. The magnetic properties of 1"CH3OH and 2 have been investigated. The variable-temperature de magnetic susceptibility studies indicate ferromagnetic Co-II...Co-II exchange interactions for 1.CH3OH and antiferromagnetic Cu-II...Cu-II couplings for 2. The ac magnetic susceptibility investigation reveals that complex 1.CH3OH shows the slow magnetic relaxation (SMM) behavior. (C) 2016 Elsevier Ltd. All rights reserved.
