高氯酸二吡啶·双(N-氯化吡啶-2-甲醛)缩-1,3-丙二胺合镍的晶体结构

Crystal Structure of Dipyridine-N , N'-Trimethylene Bis (N-Oxopicolinaldiminato) Nickel (Ⅱ)Perchlorate

合成了Ni(Ⅱ)的吡啶和双(N-氧化呲啶-2-甲醛)缩-1,3-丙二胺的配合物。对它进行了红外、紫外、电导和磁化率的表征。测定了其晶体结构。定性解释了红外特征吸收峰D_(N-O)和V_(C=N)波数移动与分子几何构型之间的关系。利用紫外吸收峰近似计算了配体场分裂参数Dq和Racah参数B。

The title complex has been synthesized and characterized by IR, magnetic susceptibility, molar conductance and UV-VIS. The crystal structure of this complex has been determined by X-ray diffraction. The relationship between the shift of IR characteristic absorption VN-O,vc-Nand geometry configuration of molecule is interpreted qualitatively. Finally,the ligand field splitting parameter Dq and Racah parameter B are calculated approximately by using UV-UIS spectra.
