Abstract
Three novel tetrathiafulvalene-based coordination polymers, [Co(H2TTFTB) (H2O)4DMF] (1), [Co6(HTTFTB)4(H2O)] (2) and [Mn4(TTFTB)4(H2O)7(DMF)] (3) (H4TTFTB = tetrathiafulvalene tetrabenzoate), were synthesized by simple solvothermal method. These complexes exhibit different topologies: complex 1 shows three-dimensional (3D) hydrogen-bonded framework (HOF) constructed by one-dimension (1D) [Co(H2TTFTB)] chains; complex 2 exhibits a porous 3D framework with three kinds of channels, which consisted of {Co3II(COO)8} SBUs connected with TTFTB4‒ ligands along [0 0 1] direction; the porous framework of complex 3 is composed of two types of helical nanotubes. Electrical conductivity (σ) measurements revealed moderate σ values for these three complexes, among which complex 3 shows the highest value of 3.17 × 10–6 S cm‒1 which is comparable to other promising conductive materials consisting of H4TTFTB ligands.
