Self-assembly directed by NH···O hydrogen bonding: a neutron study of a trilayered supramolecular array formed between 1,2-diaminoethane and benzoic acid

Abstract

The supramolecular array formed by co-crystallisation of 1,2-diaminoethane and benzoic acid is investigated by neutron diffraction; the system self-assembles into an unusual layered structure composed of two-dimensional hydrogen-bonded networks sandwiched between layers of edge-to-face stacked aromatic systems; the number of hydrogen-bond donors and acceptors is balanced in the structure.
