The six-membered-ring azomethine N-((E)-{5-[(E)-(pyridin-3-yl­imino)­meth­yl]thio­phen-2-yl}methyl­idene)pyridin-3-amine

Abstract: The title compound, C16H12N4S, forms a three-dimensional layered network structure via inter­molecular hydrogen bonding and [pi]-stacking. The azomethine molecule adopts the thermodynamically stable E regioisomer and the pyridine substituents are antiperi­planar. The mean planes of the pyridine rings and the azomethine group to which they are connected are twisted by 27.27 (5) and 33.60 (5)°. The electrochemical energy gap of 2.3 eV based on the HOMO-LUMO energy difference is in agreement with the spectroscopically derived value.

Formula: C16H12N4S

Keywords: crystal structure; hydrogen bonding; [pi]-stacking inter­actions; azomethines; optical properties; electrochemical properties.
