Organic metals

Historically the term ‘metal’ has beon applied exclusively to solids formed from one of the metallic elements or from alloys containing these elements. However, recently synthesized organic compounds such as TTF-TCNQ have been found to exhibit metallic properties over a wide tomperature range and yet are composed solely of non-metallic atoms such as carbon, nitrogen, sulphur and hydrogen. The organic molecules which form these compounds are …
