Radical cation salts of TTF(CH2OH)4 with cyanide anions: Synthesis, crystal structure and magnetic properties of [TTF(CH2OH)4][TCNQF4] and [TTF(CH2OH)4]3[18-crown-6 ⊂ K][M(CN)6] · DMF (M = Fe, Co)

The synthesis, crystal structures and magnetic properties of radical cation salts formulated [TTF(CH2OH)4][TCNQF4] and [TTF(CH2OH)4]3[18-crown-6 ⊂ K][M(CN)6] · DMF (M = Fe, Co) are described. In these salts, associating the tetrakis(hydroxymethyl)tetrathiafulvalene with cyanide anions, the organic molecules are combined in oligomers and strong hydrogen bonds occur between them and the anions.
