Abstract:
The crystal structure analysis of N-(p-methoxyphenyl-3-propyl)-p-bromobenzamide was carried out by means of X-rays. This compound crystallizes in two crystalline polymorphs, both belonging to the monoclinic system. α-form:a=14.592,b=9.572,c=11.242Å,β=94.26°;Z=4;space groupP21c β-form:a=11.940,b=10.019,c=6.577Å,β=90.56°;Z=2;space groupP21. A little difference in structure is observed between the molecules in the two polymorphs, while the conformations of the carbon-carbon bonds in the 3-aminopropyl group are of the trans form. In both forms, belts of molecules parallel to the b axis are formed by hydrogen bonds between the amide groups of the molecules related by the twofold screw axis. These belts are packed anti-parallel in the α-form, but parallel in the β-form.
