Cl3O6C21H21,Mr=475.75, orthorhombic,P212121,a=21.895(3),b=12.101(2), andc=8.237(2) A,V=2182.4(7) A3,Dx=1.45 g cm−3 forZ=4, λ(MoKα)=0.71069 Aμ=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 acis diaxal configuration of hydrogen atoms in the 9, 10 positions, confirming the 13-C NMR results.
