摘要
用乙酰丙酮和氧化铁直接反应合成了配合物乙酰丙酮铁,取得的CCDC(Cambridge Crystallographic Data Centre)编号是693046。通过红外光谱、紫外可见光谱对其进行了表征,并用X射线单晶衍射测定了其晶体结构。结果表明,该晶体属于正交晶系,空间群为Pbca,晶体相关参数分别为:a=1.549 4(5)nm,b=1.359 5(5)nm,c=1.658 9(5)nm,α=β=γ=90,°V=3.494(2)nm3。配合物中心Fe3+均与三个乙酰丙酮负离子发生双齿配位,形成轻微畸变的八面体构型。
The single crystal Fe（acac）3 was successfully synthesized using acetylacetone and ferric oxide as the starting materials.The number of acetylacetonate in CCDC is 693046.It was characterized by IR,UV-Vis and X-ray single crystal diffraction.The result indicated that the crystal has an orthorhombic structure with space group Pbca and the crystallographic data of the complex are ： a = 1.549 4（5）nm,b = 1.359 5（5）nm,c = 1.658 9（5） nm,α=β=γ=90°,V =3.494（2） nm3,Fe（Ⅲ） ion is coordinated with six oxygen atoms from three Hacacs,and form a slightly distorted octahedron coordination geometry.
