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

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.
