[(E)-1-(Naphthalen-2-yl)ethylidene](naphthalen-1-ylmethyl)amine

S. M. Bruno, J. A. Fernandes, I. S. Gonçalves and F. A. Almeida Paz

Abstract: The title compound, C23H19N, was obtained unexpectedly from the reaction of [Eu(nta)3(PzPy)] {Hnta = 1-(2-naphthoyl)-3,3,3-trifluoroacetone and PzPy = 2-[3(5)-pyrazolyl]pyridine} with 1-naphthylmethylamine. The 1- and 2-naphthyl groups are essentially planar [r.m.s. deviations of 0.007 and 0.011 Å, respectively] and subtend angles of 38.69 (11) and 16.50 (11)°, respectively, with the central CH3-C=N-CH2 unit, which is also almost planar [r.m.s. deviation = 0.002 Å]. In the crystal, the molecules are disposed in zigzag-type fashion, forming layers perpendicular to [100]. Weak supramolecular C-H...[pi] interactions contribute to the packing forces.
