Abstract

The atomic distance between shrunken atoms in five representative organic charge-transfer superconductors, (TMTSF)2C104 β-(BEDT-TTF)2I3, β-(BEDT-TTF)2IBr2, κ-(bedt-ttf)2 cu[n(cn)2](NCS)2 and K3C60 were calculated and the shrunken atoms were related to Tc in comparison with inorganic superconductors. The main role of charge transfer force between the cation stack and the insulating layers of anion in the organic superconductors is a compression of the spherical inner paired electron clouds toward to the nucleus, the so-called pintch effect. Tc increases as the pintch effect increases. The electron pair set, 3d10and 2p6, derived from the compressed atoms, Se and S, respectively, in organic superconductors can be explained as an origin of superelectrons, as well as superconducting inorganic compounds and elements.
