结论相应的Ni(II)物种经60Coy辐照后，在固相中生成了光谱可检测到的Ni(III)四氮杂-巴豆环配合物。这些d7离子中的单个未配对电子主要位于Ni(3dz2)原子轨道上，该轨道与未损伤晶格的NiN4平面垂直方向相差几度。新的z轴靠近Ni-0C103方向表明，Ni(III)的形成伴随着晶格重排，这导致了镍离子的初始八面体配位。
ConclusionSpectroscopically detectable amounts of Ni (III) tetraazama-crocycle complexes are generated in the solid state by 60Co y irradiation of the corresponding Ni (II) species. The single un-paired electron in these d7 ions is principally located in a Ni (3dz2) atomic orbital which is directed a few degrees away from the perpendicular to the NiN4 plane of the undamaged lattice. The proximity of the new z axis to Ni-0C103 directions suggests that Ni (III) formation is accompanied by a lattice rearrangment which results in incipient octahedral coordination of the nickel cation.
