H-bonding schemes of di- and tri-p-benzamides assessed by a combination of electron diffraction, X-ray powder diffraction and solid-state NMRCCDC reference numbers 750010 and 750011. For crystallographic data in CIF or other electronic format see DOI: 10.1039/b920569a

The crystal structures of di- and tri- p -benzamides are solved by a combination of single crystal, electron and powder X-ray diffraction. Different hydrogen-bonding schemes observed in the two structures are described and classified. The hydrogen-bonding networks are correlated to complementary data obtained from multinuclear solid-state NMR.
