The compound 3,3'-(anthracene-9,10-diyl)bis(1-phenylpropan-1-one) (C32H26O2,Mr=442.55) has been synthesized by the reaction of 2,2'-(anthracene-9,10-diylbis(methy-lene))bis(1,3-diphenylpropane-l,3-dione) with CsCO3,and its structure was characterized by 1H NMR and single-crystal X-ray diffraction.The crystal of the title compound belongs to monoclinic,space group P21/C with a=9.154(3),b=5.2777(16),c=24.897(7) nm,β= 107.337(10)°,Z=2 and V= 1.1482 nm3.X-ray analysis indicates that an intermolecular hydrogen bond C(8)-H(8A)…O(1),weak C-H…π between H(9A) and the centre of anthracene rings and weak π-π interactions between two anthracene ring planes are observed.
