compounds, [M(PM-L)2(NCS)2], with large aromatic ligands (PM-L) and a divalent metal ion (MII=Mn, Fe, Co, Ni and Zn) have been synthesized. The magnetic data are consistent with divalent metal ions in an octahedral ligand field environment. Hyper-Rayleigh scattering measurements show an enhancement of the molecular hyperpolarizabilities (β) from Ni compounds (with two unpaired electrons) to Mn compounds
一系列具有大的芳香族配体(PM-L)和二价金属离子(M II = Mn,Fe,Co,Ni和Zn)的配位化合物[M(PM-L)2(NCS)2 ]合成的。磁数据与八面体配体场环境中的二价金属离子一致。超瑞利散射测量表明,分子的超极化率(β)从Ni化合物(带有两个不成对的电子)到Mn化合物(五个不成对的电子)增强了。对于Fe(II)金属离子,报道了配体对β值的影响。这项工作为基于自旋交叉现象的可转换材料的设计提供了有吸引力的信息。
