摘要: 本文合成了一个二价钴配合物[CoL25(NCS)2],(配体L5=4-对溴苯基-3,5-二(2-吡啶基)-1,2,4-三氮唑)。其结构由单晶X衍射结构分析,红外和电喷雾离子质谱表征。该配合物晶体属于三斜晶系,空间群为P1,钴原子和2个三芳基三氮唑配体的4个氮原子(平面)和2个硫氰根的氮原子(轴向)配位形成扭曲的八面体构型。磁性测定表明在1.8~300 K的温度范围内该配合物处于高自旋态。 |

Abstract: A new cobalt(Ⅱ) complex, [CoL25(NCS)2], [L5=4-( p-bromophenyl)-3,5-bis(2-pyridyl)-1,2,4-triazole], was synthesized and its structure was determined by single crystal X-ray diffraction, FTIR and ESI-MS spectroscopy. The complex crystallizes in triclinic system with space group P1. The cobalt atom is in a distorted octahedral environment with two bidentate chelating L ligands in the equatorial plane and two NCS- ions in the axial positions. Magnetic measurements show that the complex is in a high-spin state in the 1.8~300 K range. CCDC: 668715. |
