Abstract
This describes the following five novel organic substances: Bis (ethylenedithio) tetrathiafulvalene (henceforth to be called BEDT-TTF) compounded with cyanometalate anions in what is called Tetracyano Nickel acid Bis (Ethylenedithio) Tetrathiafulvalene salt.hydrate expressed by (BEDT-TTF).sub.4 [Ni(CN).sub.4 ].H.sub.2 O, Tetracyano Platinum acid Bis (Ethylenedithio) Tetrathiafulvalene salt.hydrate that is expressed by (BEDT-TTF).sub.4 [Pt(CN).sub.4 ].H.sub.2 O, Cyanide Palladium Bis (Ethylenedithio) Tetrathiafulvalene salt that is expressed by (BEDT-TTF)-[Pd(CN).sub.2 ], Tetracyano Palladium acid Bis (Ethylenedithio) Tetrathiafulvalene salt.hydrate that is expressed by (BEDT-TFF).sub.4 [Pd(CN).sub.4 ].H.sub.2 O and Tetracyano Palladium acid Bis (Ethylenedithio) Tetrathiafulvalene salt that is represented by (BEDT-TTF).sub.4 [Pd(CN).sub.4 ]. BEDT-TTF, acting as a common constituent in the crystals of all of the above substances, provides the properties of an insulator, a metal or a superconductor. Anions that construct the framework of BEDT-TTF determine the arrangement of BEDT-TTF and thus the electronic state of the compound. It can be predicted that superconducting phenomena could be discovered in compounds of BEDT-TTF type in which there are compounded cyanometalate anions that have the tendency to form large frameworks so that the effective volume is large as in the case of the novel substances of the present invention.
