organic compounds
The crystallographic analysis of the title compound, C12H28N+·ClO4−, (I), shows that intermolecular C—HO interactions stabilize the crystal structure. The compound is isomorphous with tetra-n-propylammonium iodide, whose structure has been described by Yoshida et al. [Acta Cryst. (1994). C50, 1758–1760].
organic compounds
The title compound, C28H44N2, is one of the precursors of the amphiphilic heteroleptic ruthenium(II) sensitizer for DSC (dye-sensitized solar cells), and its molecule has a crystallographically imposed centre of symmetry. A segregated packing structure between the alkyl chain layers and pyridine rings is observed.
