Abstract

The existence of superconductivity in chiral molecular systems is suggested by studies of the title compound. The work, which is an important extension of studies of recently organic superconductors based on unsymmetrical molecules, shows that a sudden, but incomplete loss of resistivity (by a factor of 500) takes place at 3 K and 5 kbar. Both this behavior and the crystal-packing motif suggest that the transition is of a superconducting nature.
