Inorganic chemistry, 45(11), 4372-4380 (2006-05-23)
Synthesis and crystal structure of a tren-based amide, L(1), N,N',N''-tris[(2-amino-ethyl)-3-nitro-benzamide] is reported. The crystallographic results show intramolecular hydrogen bonding and aromatic pi...pi stacking among tripodal arms which prevent opening of the receptor cavity. Intermolecular hydrogen bonding in L1 generates the
