A cocrystal of acridine with 2,4-dihydroxybenzaldehyde (2:1 stoichiometric ratio) was synthesized, spectrally and structurally characterized using TG, DSC, ATR-FTIR Single-Crystal XRD methods Hirshfeld surface analysis, its nonlinear optical properties were investigated by DFT at the B3LYP/6-311++Glevel. The obtained compound crystallizes in noncentrosymmetric P21 monoclinic space group, two molecules one molecule asymmetric unit. strong O(aldehyde)-H⋯N(acridine) weak C(aldehyde)-H⋯O(aldehyde) hydrogen bonds, as well π(acridine)-π(acridine) C(acridine)-H⋯π(aldehyde) interactions, are present crystal lattice title compound. calculated energy gap (ΔE) between HOMO-LUMO surfaces shows charge transfer interactions due to π-π* transitions among molecules. first second hyperpolarizability values indicate that is a promising candidate for applications.
