Cu(2+) doped single crystals of [Zn(sac)2(dmen)] (sac: saccharinate, dmen: N,N'-dimethylethylendiamine) and [Zn(sac)2(paen)], (paen: N,N'-bis(3-propylamine)ethylendiamine) complexes have been investigated by electron paramagnetic resonance (EPR) technique. Detailed investigations of the EPR spectra indicate that Cu(2+) ion substitute with Zn(2+) ion and forms tetrahedral complex in [Zn(sac)2(dmen)] and octahedral complex in [Zn(sac)2(paen)] hosts. Principal values of the g and hyperfine tensors are determined and the ground state wave functions of Cu(2+) ions are obtained using EPR parameters.
已通过电子顺磁共振（EPR）技术对掺杂Cu(2+)的[Zn(sac)2(dmen)]（sac：糖精，dmen：N,N'-二甲基乙二胺）和[Zn(sac)2(paen)]（paen：N,N'-双(3-丙胺)乙二胺）配合物单晶进行了研究。对EPR光谱的详细研究表明，Cu(2+)离子取代了Zn(2+)离子，并在[Zn(sac)2(dmen)]中形成四面体配合物，在[Zn(sac)2(paen)]主体中形成八面体配合物。确定了g和超精细张量的主值，并利用EPR参数获得了Cu(2+)离子的基态波函数。
