1- N -(4-pyridylmethyl)amino naphtalene was synthesized by means of a reaction of alpha-naphthylamine, 4-pyridylcarboxyaldehyde, in anhydrous ethanol to obtain N -(4-pyridylen)-alpha-naphthylamine and that was reduced with NaBH 4 to produce the wanted compound. The X-ray powder diffraction pattern for the new compound 1- N -(4-pyrydylmethyl)amino naphtalene was obtained. This compound crystallizes in a monoclinic system with refined unit cell parameters a =10.375(5) Å, b =17.665(6) Å, c =5.566(2) Å, β=100.11(3), and V =1004.3(5) Å 3 , with space group P2/m (No. 10).
