The title compound, C13H14N4O, has been synthesized as an ADDA (D: hydrogen
-bond donor; A: hydrogen-bond acceptor) recognition unit for quadruple hydr
ogen bonds. In the solid state, it crystallizes as a centrosymmetric dimer
connecting one N-H group with one pyridyl N atom. Furthermore, an intramole
cular hydrogen bond is formed connecting two N atoms.
