摘要：

The compounds taken in this paper to make a comprehensive review are imperatorin, phellopterin, rutaretin, marmesin and bergapten. The aim of this research paper is to confirm the aromatic character of these compounds and to find the different type interactions responsible to assemble the molecules into supramolecular structure. The pyrone moiety of all these molecules is perfectly planar with maximum deviation of 0.009(2)angstrom. In all the crystals, molecules are linked by C-H center dot center dot center dot O hydrogen bonds, forming a three dimensional framework. Different structural motifs (chains, dimmers, rings, etc.) bonded with C-H center dot center dot center dot pi and pi center dot center dot center dot pi interactions are analysed, which leads them into supramolecular structures.
