Title: Soft And Hard Molecule-based Magnets Of Formula [bu4n] 2[m2{cu(opba)}3]. Dmf [m = Mn(ii) Or Co(ii), Opba = Ortho-phenylenebis(oxamato), Dmf = Dimethylformamide]

Abstract: The compounds of formula [Bu4N]2[Mn 2{Cu(opba)}3] . 4DMF.5H2O (BMn) and [Bu 4N]2 [Co2{Cu(opba)}3]. DMF.H 2O (BCo) have been synthesized (opba = ortho-phenylenebis(oxamato)). BMn shows a spontaneous magnetization below a critical temperature Tc equal, to 22 K; for BCo, Tc = 40 K, the strongest for this type of system. While BMn is a soft magnet, BCo exhibits a coercive field, of 4kOe. © 2001 Elsevier Science B.V. All rights reserved.
