1-(4-Aminophenyl)-3-(3-bromophenyl)prop-2-en-1-one

Abstract

The title mol­ecule, C15H12BrNO, is approximately planar and the dihedral angle between the two aromatic rings is 9.6 (1)°. The crystal packing reveals that the mol­ecules translated by one unit cell along the a‐axis direction are linked into a chain by inter­molecular N—H⋯O and C—H⋯O hydrogen‐bonding inter­actions. The screw‐related mol­ecules of adjacent chains are linked via N—H⋯N hydrogen bonds into a sheet‐like structure parallel to the ab plane.

“…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 .…”

“…Recently it has been noted that bromo-substituted derivatives of chalcones exhibit extremely high and fast nonlinearity (Fichou et al, 1988;Zhang et al, 1990;Zhao et al, 2000), and show preferences to crystallize as non-centrosymmetric structures. For this reason, they have been the objective of several experimental and theoretical studies, aimed mainly at the determination of their crystal structures (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;Radha Krishna et al, 2005;Uchida et al, 1995). We report here the synthesis and crystal structure of the title compound, (I).…”

“…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) .…”

1,3-Bis(4-bromophenyl)prop-2-en-1-one

“…The bond lengths and angles in (I) have normal values (Allen et al, 1987) and are comparable to those of related structures (Jeyabharathi et al, 2002;Ng et al, 2006a,b;Ravishankar et al, 2005;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;Teh et al, 2006). The difference in the C1-C6-C7 [122.7 (3) ] and C6-C7-C8 [118.4 (2) ] angles is due to the short H1AÁ Á ÁH8A (2.29 Å ) contact.…”
