摘要
合成了一个锰的水杨醛乙二胺Schiff碱的配合物,并分别用元素分析、红外光谱、X-单晶衍射仪等手段对该配合物进行了表征。配合物化学式为C16H14MnN5O2,式量为363.26。配合物属单斜晶系,Pca2(1)空间点群。晶胞参数:a=10.9590(8),b=12.9699(9),c=11.1316(8)。中心离子呈变形的八面体几何结构,与Schiff碱的N、O原子配位,又与叠氮根离子的N原子形成1,3桥连的一维链状结构。
A salicylaldehyde schiff base manganese (Ⅲ) coordination polymer [ Mn( N3 ) (sal-en) ]n ( Sal = salicylaldehyde, en = ethylenediamine) has been synthesized and characterized by elemental analysis, infrared and X-ray diffraction. Its empirical formula is C16H14MnN5O2, molecular weight is 363.26, and it crystallizes in the orthorhombic, space group is Pca2(1), the crystal parameters are: a = 10.9590(8) A, b = 12.9699(9) A, c = 11. 1316(8) A. The oxygen and nitrogen atoms from salicylaldehyde Schiff base ligand are coordinated to the central Mn(Ⅲ) ion in a octahedral geometry mode, while the azide ion is coordinated in a 1, 3 bidentate-bridging mode. The complex displays a one-dimensional single-chain polymer.
