4-Ethynyl-N,N-diphenylaniline

Abstract

The asymmetric unit of the title compound, C20H15N, comprises two crystallographically independent molecules (A and B). In each molecule, the N atom adopts an approximately trigonal planar geometry, lying 0.009 (1) or 0.003 (1) Å from the plane defined by the C atoms of the aromatic substituents to which it is attached. In the crystal, molecules are linked via C—H...π interactions, forming a three-dimensional structure.
