本文报道了两种海因类铜配合物的合成和光谱性质。合成了通式为Cu(hyd)_2(py)_2的配合物,其中hyd =苯妥英或尼凡诺,py =吡啶,并用红外光谱和ESR对其进行了表征。光谱数据显示铜原子与乙内酰脲阴离子的氮原子和吡啶分子的氮原子结合,形成2:2:1的乙内酰脲:吡啶:铜络合物。ESR数据表明,两种配合物都具有四电子对称性(g11> g> ge),未成对电子位于dx2− y2轨道。
The preparation and spectral properties of copper(II) complexes of two hydantoins are reported. Complexes of the general formula Cu(hyd)2(py)2, where hyd = phenytoin or nirvanol; and py = pyridine were prepared and characterized by infrared and ESR. Spectral data show that the copper atom is bound to the nitrogen atom of the hydantoin anion and to the nitrogen atom of the pyridine molecule to form 2:2:1 hydantoin:pyridine:copper complexes. The ESR data indicate that both complexes have tetragonal symmetry (g11> g⊥> ge) with the unpaired electron in the dx2− y2orbital.
