Supramolecular synthons based on N-H...N and C-H...O hydrogen bonds. Crystal engineering of a helical structure with 5,5-diethylbarbituric acid

Chem Commun (Camb). 2002 Sep 7:(17):1830-1. doi: 10.1039/b204388b.

Abstract

5,5-Diethylbarbituric acid is a convenient molecular precursor for a newly identified N-H...N/C-H...O synthon, which is robust enough for the design of a helix architecture.
