本文合成了含N原子的三齿配体2,6-吡啶二噁唑啉(Pybox),由Pybox与NiCl2.6H2O和KSCN在甲醇溶液中反应制得标题配合物Ni(Pybox)(SCN)2(CH3OH),并进行了元素分析、红外光谱、电子光谱、X-射线衍射等表征。结果表明:此配合物属单斜晶系,空间群为P2(1)/n,晶体学参数为:a=7.9514(14),b=12.565(2),c=17.992(3),β=92.603(3)°,V=1795.7(5)3,Z=4,μ=1.336 mm-1,F(000)=872,Dc=1.569 g/cm3。配合物中的金属镍离子位于非对称中心,分别与一个Pybox中的三个N原子、两个SCN-离子中的N原子和一个CH3OH分子的O原子配位,形成畸变的八面体配位结构。

The tri-connecting ligand containing N-donors of 2,6-bis（oxazolinyl）pyridine was synthesized,the complex Ni（Pybox）（SCN）2（CH3OH）was prepared by the reaction of Pybox with CoCl2·6H2O and KSCN in methanol,and the complex was characterized by elemental analysis,IR spectra,electronic spectra and X-ray diffraction.The results showed that the title complex belonged to mono-clinic system with P2（1）/n space group and cell parameter：a=7.9514（14）,b=12.565（2）,c=17.992（3）,β=92.603（3）°,V=1795.7（5）3,Z=4,μ=1.336 mm-1,F（000）=872,Dc=1.569 g/cm3.The asymmetric complex formed distorted octahedral geommetry through coordination of Ni（II）with three N atoms of one 2,6-bis（oxazolinyl）pyridine,two N atoms of thiocyanate anions and one O atom of methanol molecule.
