Abstract
The crystal structure of a protonated Schiff base, isolated as its nitrate salt, exhibits a supramolecular chain-like architecture that propagates along the crystallographic b-axis direction and features intermolecular O—H⋯O and C—H⋯O hydrogen-bonding.
The crystal structure of the title salt, C20H27N2O+·NO3−, has a cationic (E)-mesityl-N-[4-(diethylamino)benzylidene]benzenaminium species and a nitrate counter-ion in the asymmetric-unit. In the crystal, alternating intermolecular O—H⋯O and C—H⋯O hydrogen-bonding occurs between neighbouring protonated Schiff bases and nitrate ions within a supramolecular, chain-like architecture that extends along the crystallographic b-axis direction.
