We have synthesized the tolane derivative 3-n-propylamide-4-(4- hexyloxyphenylethynyl)-nitrobenzene 1 and examined its second-order nonlinear properties and crystal structure. Compound 1 crystallizes in the space group Clc1 with a = 27.667(6), b = 4.910(2), c = 20.856(3) A, β = 128.36(3)°and Z = 4, and shows a high second-order nonlinear optical efficiency. It has an intermolecular hydrogen bond between C=O and N-H in the amide group. This hydrogen bond plays an important role in forming a non-centrosymmetric structure appropriate for nonlinear optical materials.
