摘要
合成了三（３－羟基黄酮）合铝（Ⅲ），制得［Ａｌ（Ｃ１５Ｈ９Ｏ３）３］２·２ＣＨＣｌ３·８Ｈ２Ｏ晶体，Ｘ射线衍射结果表明：其结构属于三方晶系，空间群为Ｒ３．晶胞参数：ａ＝ｂ＝１．６５５８（３）ｎｍ，ｃ＝３．６４６５（２０）ｎｍ，α＝β＝９０°，γ＝１２０°，Ｖ＝８．６５６０８（０．００５８６）ｎｍ３，Ｄｃ＝１．４５ｇ／ｃｍ３，μ（ＭｏＫα）＝３．２０ｃｍ－１，Ｆ（０００）＝３９２４．分子中每个３－羟基黄酮以其独特的酮基和羟基同时与Ａｌ３＋配位。
Al(C 15 H 9O 3) 3 2\52CHCl 3\58H 2O was synthesized, and its crystal structure was determined. It belongs to trigonal system, R3 , a=b =1.655 8(3) nm, c =3.646 5(20) nm, α=β=90°, γ=120°, V =8.656 08(0.005 86) nm 3. D c=1.45 g/cm 3, μ(Mo Kα )=3.20 cm -1 , F (000)=3 924. The crystal structure was solved by Patterson and Fourier techniques, and refined by a block diagonal least squares method. A total of 3 737 independent intensity data were collected, of which 1 033 with I ≥3σ( I 0) were observed, R=0.091 8, R w= 0.091 8 . Al 3+ ion was 6 coordinated, bound to six oxygen atoms from three 3 hydroxyflavones to form a distortional coordination octahedron.
