LI, X.H.; JALBOUT, A. F.  and  XIANG, W.D.. Self-assembly of supermolecular species directed by hydrogen bonding and aromatic π-π stacking interactions. Eclet. Quím. [online]. 2008, vol.33, n.2, pp. 13-19. ISSN 0100-4670.  http://dx.doi.org/10.1590/S0100-46702008000200002.

A new Cu(II) trimers, [Cu₃(dcp)₂(H₂O)₈]. 4DMF, with the ligand 3,5-pyrazoledicarboxylic acid monohydrate (H₃dcp) has been prepared by solvent method. Its solid-state structure has been characterized by elemental analysis, thermal analysis (TGA and DSC), and single crystal X-ray diffraction. X-ray crystallographic studies reveal that this complex has extended 1-D,2-D and 3-D supramolecular architectures directed by weak interactions (hydrogen bond and aromatic π-π stacking interaction) leading to a sandwich solid-state structure.

Keywords : Copper complex; crystal structure; supramolecular; π-π interaction.
