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,3个配体中的6个配位氧原子形成扭曲的配位八面体.

Abstract: Al[(C15H9O3)3]2·2CHCl3·8H2O was synthesized, and its crystal structure was determined. It belongs to trigonal system, R3, a=b =1.6558(3) nm, c =3.6465(20) nm, α=β=90°, γ=120°, V =8.65608(0.00586) nm3. Dc=1.45 g/cm3, μ(Mo Kα)=3.20 cm-1, F (000)=3924. The crystal structure was solved by Patterson and Fourier techniques, and refined by a block-diagonal least-squares method. A total of 3737 independent intensity data were collected, of which 1033 with I ≥3σ( I0) were observed, R=0.0918, Rw= 0.0918. Al3+ ion was 6-coordinated, bound to six oxygen atoms from three 3-hydroxyflavones to form a distortional coordination octahedron.
