| Popis: | Item does not contain fulltext New ethylenedithiotetrathiafulvalene (EDT-TTF)-based radical cation salts with mercury containing anions of different size and shape have been isolated and studied. Among these compounds the new ambient pressure organic superconductor (EDT-TTF)(4)Hg3-deltaI8, deltasimilar to0.1divided by 0.2, with T-c=8.1K has been synthesized. Depending on a EDT-TTF/HgI2 ratio, electrochemical crystallization of EDT-TTF affords either hexagonal (EDT-TTF)(4)Hg3+/-deltaI8, (delta-0.1divided by0.2) or rectangular (EDT-TTF)(2)Hgl(3) crystals. Three types of hexagonal crystals were certified using conductivity ineaSUrenients: the crystals with superconducting temperature Tc=8.1K under ambient pressure (1), those undergoing a superconducting transition at 5 |
