ligand 5,5′-bis(4,5-bis(thiomethyl)-4′-carbamoyltetrathiafulvalene)-2,2′-bipyridine (L) has been tested with Cu(I) and Cu(II) centres. [(L)2CuI](PF6), [(L)2CuII](OTf)2 and [(L)CuII(DMF)3](OTf)2 have been synthesized. A single-crystal X-ray analysis was performed on [(L)CuII(DMF)3](OTf)2, showing a distorted octahedral geometry around the Cu(II) centre, and the formation of dimeric units in the solid state
基于电活性TTF的螯合剂的配位能力 配体已经用Cu(I)和Cu(II)中心测试了5,5'-双(4,5-双(硫甲基)-4'-氨基甲酰基四硫富瓦烯)-2,2'-联吡啶(L)。合成了[(L)2 Cu I ](PF 6),[(L)2 Cu II ](OTf)2和[(L)Cu II(DMF)3 ](OTf)2。单晶X射线分析对[[ L)Cu II(DMF)3 ](OTf)2进行了分析,显示了Cu(II)中心周围的八面体形畸变,并且通过在末端的弱配位形成了固态的二聚体单元酰胺来自相邻络合物的氧原子。磁数据表明,顺磁性金属中心是隔离的,与固态结构一致。对这三种络合物进行了电化学测量,并且在所有情况下均观察到了Cu(I)/ Cu(II)和TTF / TTF + ˙/ TTF 2+氧化还原过程。
