“…In (I) ( Fig. 1), the bond lengths and angles have normal values (Allen et al, 1987), comparable with those found in related structures (Teh et al, 2006;Patil et al, 2006a,b;Ng et al, 2006;Rosli et al, 2006). The least-squares plane through the enone group makes dihedral angles of 4.19 (5) and 2.14 (6) , respectively, with the benzene and furan rings.…”
