N,N '-bis(2-tosylaminobenzylidene)-1,3-propanediamine

The conformation of the title molecule, C(31)H(32)N(4)O(4)S2(,) in the soli d state is strongly influenced by intramolecular hydrogen-bond interactions (N-H ... N), which probably minimize the steric hindrance of the tosyl gro ups. The molecule is not planar and with long distances between aminic N at oms [7.724(3) Angstrom], a major change in conformation will be required fo r it to act as a tecradentate ligand via its four N atoms.
