Self-assembly of supermolecular species directed by hydrogen bonding and aromatic π-π stacking interactions

Abstract

Abstract:A new Cu(II) trimers, [Cu 3 (dcp) 2 (H 2 O) 8 ]. 4DMF, with the ligand 3,5-pyrazoledicarboxylic acid monohydrate (H 3 dcp) 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.
