Br−, NCS− and N−3 completes the bonding to the Cu(II) center of these 4-coordinate complexes. When the complexes are prepared using Cu(II) perchlorate, the solids isolated contain a neutral thiosemicarbazone ligand as well as the deprotonated ligand. The solids are primarily characterized by IR, electronic and electron spin resonance spectroscopy. In addition, electronic and ESR spectra of their chloroform
摘要硫半脲,3-氮杂双环[3.2.2]-壬烯-3-硫代羧酸2- [1-(2-吡啶基)亚乙基]酰肼(HL)和相应的N-氧化物的一系列Cu(II)配合物(HLO)已经准备好并进行了表征。两种配体均经历去质子化并似乎通过硫酮硫,亚胺氮和吡啶基氮(或N-氧化物氧)配位。单个阴离子配体(例如Cl-,Br-,NCS-和N-3)完成与这些4配位配合物的Cu(II)中心的键合。当使用高氯酸铜(II)制备配合物时,分离出的固体含有中性的硫代半碳酰胺配体以及去质子化的配体。固体的主要特征在于IR,电子和电子自旋共振光谱。此外,还记录了其氯仿溶液的电子和ESR光谱。溶解后,大多数固体(硝酸盐除外)保持不变。溶液ESR光谱的模拟用于估算各种配位核的耦合常数。
