1,4-Diphenyl-1,4-di-4-pyridyl-2,3-diaza-1,3-butadiene: weak C-H...N and C-H...pi hydrogen bonds.
In the title compound, C24H18N4, each Schiff base molecule is centrosymmetric and interacts with four neighbours via four C-H(Ph)...N(py) hydrogen bonds (py is pyridyl) and four C-H(py)...pi(Ph) hydrogen bonds, leading to an interesting two-dimensional hydrogen-bonded layer architecture.
