N,N'-Bis(pyridin-4-ylmethyl)terephthalamide dihydrate: a self-interpenetrating hydrogen-bonding network

H.-T. Zhang and X.-Z. You

Abstract: The title compound, C₂₀H₁₈N₄O₂·2H₂O, has an inversion center at the mid-point of the central benzene ring. The asymmetric unit consists of one-half of an N¹,N⁴-bis(pyridin-4-ylmethyl)terephthalamide molecule and one water molecule. The intermolecular hydrogen bonds connect the amide molecules and water molecules to produce a self-interpenetrating hydrogen-bonding network. The crystal packing is also governed by intermolecular - stacking and a weak C-H interaction.
