  Synthesis, spectral, magnetic and electrochemical properties of new dimeric copper(II) complexes

  摘要：

  Four new ligands, bis-[3,5-disubstituted-2-hydroxybenzyl]-N-alkylamines (L-1-L-4) with three potential donor sites, capable of forming dimeric copper(II) complexes have been prepared. The dimeric nature of the complexes has been confirmed by FAB mass spectral studies. Molar conductance studies indicate that the complexes are neutral. Electrochemical studies indicate that the complexes undergo quasi reversible two step single electron transfers at negative potentials (E-pc(1)=-0.34 to -0.48 V, E-pc(2)=-0.59 to -0.72 V). Variable temperature magnetic studies indicate that the complexes are antiferromagnetically coupled (-2J=290 to 400 cm(-1)). ESR spectral studies in DMF indicate that the complexes are dimeric and undergo dissociation on addition of pyridine. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Two bis(mu-phenoxo)dicopper(II) complexes, [(L(CH3))(2)Cu(2)] (1) and [(L(t-Bu))(2)Cu(2)] (2), where L(CH3) and L(t-Bu) represent the dianions of (methylamino)-N,N-bis(2-methylene-4,6-dimethylphenol) and of (methylamino)-N,N-bis(2-methylene-4,6-di-tert-butylphenol), respectively, are reported to demonstrate the effect of remote substituents on the nature of exchange coupling interactions between the

  [[L（CH3））（2）Cu（2）]（1）和[[L（t-Bu））（2）Cu（2）]两个双（mu-phenoxo）dicopper（II）络合物（ 2），其中L（ ）和L（t-Bu）表示（甲基氨基）-N，N-双（2-亚甲基-4,6-二甲基苯酚）和（甲基氨基）-N，N-双的二价阴离子（2-亚甲基-4,6-二叔丁基苯酚）分别被证明来证明远程取代基对铜（II）中心之间的交换耦合相互作用的性质的影响。与通常进行反铁磁耦合的1相比，复合物2是铁磁耦合的二苯氧二铜（II）配合物的罕见实例。
