| 摘 要： | 本文合成了两个新型Co(Ⅱ)配合物，LCo(μ-C2O4)CoL]·(ClO4)2·2CH3CN (1)和CoL(SCN)]·ClO4 (2)，其中，L即三(3，5-二甲基吡唑甲基)胺。在配合物1中，Co与来自三脚架配体的4个氮和草酸根桥联配体的2个氧原子配位，处于扭曲八面体配位环境。由草酸根桥联两套LCo，构成了一个双核结构。在单核配合物2中，Co(Ⅱ)处于三角双锥配位构型，SCN-通过N配位与中心离子Co(Ⅱ)键联。在同一晶胞中有两个构型略微不同的分子，两个分子之间通过SCN的S原子有弱相互作用。对化合物1和2在溶液中的光谱性质做了进一步的研究和讨论。

| Abstract: | Two novel cobalt complexes, LCo(μ-oxalate)CoL)·(ClO4)2· 2CH3CN (1) and CoL(SCN)]·ClO4 (2) havebeen synthesized, and their structures have been determined by X-ray crystallography, where L is tris(3,5-dimethylpyrazol-l-yl)methyl]amine. In compound 1, Co(Ⅱ) is in a distorted octahedron environment with four nitro-gen atoms from the tripodal ligand and two oxygen atoms from the bridged oxalate, and the molecule is a dimmer-ic structure consisting of two LCo unites linked by bridging oxalate. In the monomer 2, Co(Ⅱ) center is in trigonalbipyrimad coordination configuration, a thiocyanate group is bonded to the metal center through the nitrogenatom. There are two somewhat different configurations of 2 in the unit cell, and there is a weaker interaction be-tween two molecules of 2 at sulphur atoms. The title complexes were generated by a precursor mononuclear cobaltCCDC: 244798, 1; 244799, 2. |
