The title compound 2-[1-(4-butylphenyl)-4,5-diphenyl-1H-imidazol-zyl]phenol has been synthesized by the reaction of appropriate mole quantities of 4-Butylaniline, benzil, ammonium acetate, salicylaldehyde in one pot reaction and characterized by Nuclear Magnetic Resonance (NMR) and IR techniques and finally the molecular structure was confirmed by single crystal X-ray diffraction studies. The title compound C31H28N2O crystallizes in the monoclinic crystal system, in P21/n space group with unit cell parameters, a=10.0330(3) Å, b=14.7203(4) Å, c=16.9169(5) Å, β=101.596(1) Å and Z=4. The crystal structure of the title compound exhibit CH···N and OH···N hydrogen bonding interactions and contributes to the structural stability. Molecular structure is also stabilized by CH···π interactions. Further, the Hirshfeld surface analysis; fingerprint plot reveals the percentage contribution from each individual molecular contact, and it shows that the H···H interactions has the major contribution (61.8%).
