摘要：

Cl3O6C21H21, Mr=475.75, orthorhombic, P212121, a=21.895(3), b=12.101(2), and c=8.237(2) Å, V=2182.4(7) Å3, Dx=1.45 g cm-3 for Z=4, λ(Mo Kα)=0.71069 Åμ=3.99 cm-1, F(000) 984, room temperature, R=0.035 for 1877 observed reflections. The molecule exhibits a folded conformation: the dihedral angle between the benzene rings is 28.3(1)°. The central ring is characterized by a cis diaxal configuration of hydrogen atoms in the 9, 10 positions, confirming the 13-C NMR results. © 1990 Plenum Publishing Corporation.
