摘要: 制备了两种不同基质的掺杂3dZ2基态铜(Ⅱ)苯并15冠5配合物(Cu(Ⅱ)B15C5)的粉末样品,ESR测定结果表明,以B15C5为基质时,Cu(Ⅱ)B15C5的轴向配体是H2O;而以Mg(Ⅱ)B15C5为基质时的轴向配体则是CIO4-.不同的轴向配体对ESR谱的线型有着较大的影响。利用Bleaney公式,计算了键参数,并对成键特性进行了讨论和比较。

Abstract: Two powder samples of copper(Ⅱ) benzo-15-crown-5(Cu(Ⅱ) B15C5) coniplexes with 3dZ2-ground state doublet doped in different substrathe were prepared.The ESR measurements demonstrate that H2O molecules are the azial ligands of Cu(Ⅱ) B15C5 complex doped in B15C5 substrate,whereas ClO4- ions are the ones in Mg(Ⅱ) B15C5 substrate,The line shape of ESR spectra are found to be strongly affected by the axial ligands.The copper(Ⅱ)-ligand bonding parameters are estimated from the ESR parameters by means of Bleaney formula and the bonding nature is discussed and compared.
