摘要: 本文合成了一个新的含有4-对甲基苯基-3,5-二(2-吡啶基)-1,2,4-三氮唑配体(L)的锰(Ⅱ)配合物,[MnL2(NCS)2]。其结构由X射线晶体学,红外和电喷雾离子质谱表征。在晶体结构中, 锰原子有一反演中心并由2个三芳基三氮唑配体的4个氮原子和2个反式硫氰根的2个氮原子八面体配位。磁性测定表明在75~300 K的温度范围内该配合物是顺磁性的。 |

Abstract: A novel manganese(Ⅱ) complex with 4-(p-methylphenyl)-3,5-bis(pyridin-2-yl)-1,2,4-triazole (L), [MnL2(NCS)2], has been synthesized and its structure characterized by X-ray crystallography, FT-IR and ESI-MS spectroscopy. In the structure there is an inversion center at the manganese(Ⅱ) atom which is octahedrally coordinated to four nitrogen atoms from two triaryltriazole ligands (L) and nitrogen atoms of two NCS- ions in a trans arrangement. Magnetic measurements show that the complex is high-spin species in the 75~300 K range. CCDC: 234894. |
