摘要
本文在 Mikulski 等人研究的基础上,利用 King—Kramer 配位场理论能级图,通过比较实验测定的吸收光谱,确定出了有机配位络合物 Ni(depf)_2的空间构型与光谱学参量.由此参量得出的磁矩的理论值(μ_(eff)理)与实验测定结果一致,显而易见,用这种方法确定的复杂的大分子有机络合物 Ni(depf)_2的空间结构是正确的,即该络合物的空间构型为 D_(h2)对称晶位,磁矩(μ_(eff)理)=3.20(μ_(eff)实=3.17).
By using the ligand-field energy level diagrams of King-Kremer and making a comparison between absorption spectra determined in the test, the author finds out the space stereo configuration and the spectral parameter of organic complex Ni(depf)_2·The calculated value of the magnetic moment obtained by using this spectral parameter is in agreement with observed result by Mikulski et at.Obviously,it is right to use this method for analysis of the space configuration of the organic complex Ni(depf)_2 Its space configuration is symmetric crystal D_(2h)and its magnetic moment (μ_(eff)Cal.)equals 3.20(μ_(eff)·exp.=3.17).
