title: Propane-1,3-diyl bis-(4-amino-benzoate).
abstract: Mol-ecules of the title compound, C(17)H(18)N(2)O(4), lie on a twofold rotation axis that passes through the central methyl-ene C atom. The mol-ecules adopt a 'V' shape and the trimethyl-ene unit assumes a gauche-gauche conformation. The amino N atom shows a nonplanar coordination. Adjacent mol-ecules are connected by N-H⋯O hydrogen bonds into chains running along [001]. Furthermore, N-H⋯N hydrogen bonds connect these chains into a three-dimensional network.
