摘要：
Four new dinuclear complexes of [14] N-4 macrocyclic oxamides have been synthesized and characterized, namely [Cu(mu -L-1)ML22] (ClO4)(2) . nH(2)O, where L-1 is 2,3-dioxo-5,6: 13,14-dibenzo -1, 4, 8, 11-tetraazacyclotetradeca-7,11-diene; L-2 is ethylenediamine(en), M = Cu(1), M = Ni (2); L-2 is 1,10-phenanthroline(phen), M = Cu(3), M = Ni(4). The temperature dependence of the magnetic susceptibility of (3) and (4) has been studied over the range 4.2 similar to 300K, giving the exchange integral J = -99.1 cm(-1)(3) and J = -47.0 cm(-1)(4). The results are commensurate with strong antiferromagnetic interactions between Cu-II and Cu-II or Ni-II ions.
