Halogenated C,N-diarylacetamides: molecular conformations and supramolecular assembly

P. S. Nayak, J. P. Jasinski, J. A. Golen, B. Narayana, M. Kaur, H. S. Yathirajan and C. Glidewell

In four halogenated N,2-diarylacetamides, two are isostructural in the space group P $\overline{1}$ , with molecules linked into chains of rings by a combination of N-H

O and C-H

(arene) hydrogen bonds. Molecules of the other two acetamides are linked into simple C(4) chains by N-H

O hydrogen bonds, but significant C-H

(arene) interactions are absent.

Keywords: crystal structure; acetamides; C,N-diarylacetamides; molecular conformation; supramolecular assembly; hydrogen bonding; benzyl penicillins.
