New organic superconductors from a non-TTF donor, BDA-TTP
A new pi-electron donor, 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathia-pentalene (BDA-TTP), which contains no teirathiafulvalene (TTF) molecule, produces a series ambient-pressure superconductors beta-(BDA-TTP)(2)X(X = SbF6-, AsF6-, and PF6-), in which the values of intermolecular overlap integrals suggest loose donor parking motifs.
