Structure and physical properties of a hydrogen-bonded framework based on carboxyl-substituted TTF ligand and Mn(ClO4)2

• TTF-based carboxylic acid L which is soluble has been synthesized and characterized.
• Optimized conformation and orbital diagram of L has been calculated with DFT.
• An interesting 3D supramolecular network based on L and Mn(ClO4)2 is synthesized.

The well-soluble tetrathiafulvalene carboxylic derivative [Bu4N]2[TTF(COOH)2(COO)2] (L) has been used to create the interesting 3D supramolecular network [Mn(H2O)4(CH3OH)2][TTF(COOH)2(COO)2] (1), driven by O–H⋅⋅⋅O interaction. The absorption spectra and electrochemical behavior of L and 1 have been discussed. Optimized conformation and molecular orbital diagram of L have been calculated with density functional theory.

A well-soluble TTF–carboxylic derivative L has been synthesized. By ion exchange reaction, an interesting 3D supramolecular network 1 was obtained. Their electrochemical and absorption behaviors have been measured and analyzed. The results suggest that the TTF–carboxylic ligand is useful for building intriguing supramolecular systems.Figure optionsDownload as PowerPoint slide
