1-(4-Chlorophenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one

Abstract

In the title mol­ecule, C15H11ClO2, the ketone group is in the s‐cis conformation with respect to the olefinic double bond. The two aromatic rings form a dihedral angle of 26.07 (8)°. Screw‐related mol­ecules are linked via O—H⋯O hydrogen bonds, forming a chain along the c axis. Weak C—H⋯O and C—H⋯Cl interactions interconnect the chains into a three‐dimensional network.

“…The bond lengths and angles are within normal ranges (Allen et al, 1987) and similar to those observed in other comparable structures (Jeyabharathi et al, 2002;Patil et al, 2006;Ravishankar et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Radhika et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Santhi et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Selvam et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Unnithan et al, 2005;Teh et al, 2006). The short H5Á Á ÁH8 (2.28 Å ) contact causes the bond angle C9-C10-C11 [123.08 (9) ] to deviate significantly from 120 .…”

“…The bond lengths and angles for (I) are within normal ranges (Allen et al, 1987) and are comparable to those in related structures (Sathiya Moorthi, Chinnakali, Nanjundan, Radhika et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Santhi & Fun, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Selvam et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Unnithan et al, 2005;Ravishankar et al, 2005;Teh et al, 2006;Ng et al, 2006;Patil et al, 2006). The dihedral angle between the benzene rings is 18.34 (13) .…”

“…Bond lengths and angles in (I) have normal values (Allen et al, 1987) and are comparable to those in related structures (Sathiya Moorthi, Chinnakali, Nanjundan, Santhi et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Unnithan et al, 2005;Sathiya Moorthi, Chinnakali, Nanjundan, Radhika et al, 2005;Ravishankar et al, 2005;Teh et al, 2006;Patil et al, 2006;Ng et al, 2006;Rosli et al, 2006). The least-squares plane through the enone group makes dihedral angles of 13.88 (24) and 9.78 (24) with the C1-C6 and C10-C15 benzene rings, respectively.…”
