Ethyl­ene­diammonium dichloride bis­(1,10-phen­anthroline) tetra­hydrate.

The title compound, C2H10N22+·2Cl−·2C12H8N2·4H2O, has an inversion centre located midway between the two C atoms of the ethyl­ene­diammonium cation. The 1,10-phenanthroline mol­ecules stack along the a axis, and are linked by π–π stacking inter­actions to form one-dimensional chains. These are bridged by ethyl­ene­diammonium cations, via hydrogen bonds, forming two-dimensional supra­molecular sheets parallel to the ac plane. Hydrogen bonds to chloride anions and water mol­ecules connect these two-dimensional sheets, resulting in the formation of a three-dimensional supra­molecular network. [ABSTRACT FROM AUTHOR]
