合成了一种新的钼-氧化合物[Ni(2,2u001f-bpy)3]MoO47.5H2O,用元素分析、IR和TGA- DTA等手段进行了表征,并用X射线衍射法测定了晶体结构。结果表明,该化合物属于单斜晶系,C2/c空间群,a = 23.019(5),b = 13.967(3),c = 23.510(5) u001f,b = 107.28(3),V = 7217(3) u001f3,Z = 8,Dc = 1.514 g/cm3,F(000) = 3384,Mr = 822.32,m (MoKa) = 0.934 mm-1。结构由直接法解出,全距阵最小二乘法修正,最终偏离因子R = 0.0358,wR = 0.0797。结构测定表明,结构中阴离子MoO42-与配位阳离子[Ni(2,2u001f-bpy)3]2+之间靠静电作用相结合,同时与H2O通过氢键构成无机阴离子层。
A new molybdenum-oxygen compound [Ni (2,2 u001f-bpy) 3] MoO47.5H2O has been synthesized and characterized by means of elemental analysis, IR and TGA-DTA. structure. The results show that the compound belongs to the monoclinic space group C2 / c with a = 23.019 (5), b = 13.967 (3), c = 23.510 (5) u001f, b = 107.28 (3) u001f3, Z = 8, Dc = 1.514 g / cm3, F (000) = 3384, Mr = 822.32, m (MoKa) = 0.934 mm-1. The structure was solved by the direct method, and the full distance matrix was modified by the least square method. The final deviation factor was R = 0.0358 and wR = 0.0797. The structure determination shows that the anion MoO42- and the coordination cation [Ni (2,2 u001f-bpy) 3] 2+ in the structure are combined by electrostatic interaction and form the inorganic anion layer with H20 through hydrogen bonding.
