title: 1,1'-(Propane-1,3-di-yl)bis-(3-phenyl-urea).
abstract: The title compound, C(17)H(20)N(4)O(2), has crystallographic inversion symmetry. In the crystal structure, inter-molecular hydrogen bonding between adjacent urea groups gives rise to infinite polymeric chains diagonally across the bc plane. With a centroid-centroid distance of 3.295 (2) Å, π-π stacking is present in the crystal along the same plane.
