Abstract

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. D_c=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.
