Abstract: In both title compounds, C₁₈H₂₄N₂O₂, (Ia), and C₁₈H₂₆N₂O₂²⁺·2ClO₄^-, (II), respectively, the two aryl rings are strictly parallel, with an inversion centre lying at the mid-point of each central CH₂-CH₂ bond. Molecules in (Ia) are linked into two-dimensional layers by N-HO hydrogen bonds. The component ions in (II) are joined together by a combination of N/O/C-HO hydrogen bonds and C-H and anion interactions, forming a three-dimensional network. A structural understanding of (Ia) and (II) may provide some useful information about how and why their metal-organic complexes display various biological activities and function in catalytic processes.

Formula: C₁₈H₂₄N₂O₂ and C₁₈H₂₆N₂O₂²⁺·2ClO₄^-
