In this paper, the self-assembling characteristics of a series of L-glutamate-based ammonium amphiphiles are studied in ionic liquids ... enriched amphiphiles form fibrous bilayer assemblies ...

The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.

An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The positive and negative ions attract each other and form the ionic compound ...
