Tetrathiafulvalene-based radical cation salts with transition metal bis(dicarbollide) anions
Abstract
Radical cation salts based on derivatives of tetrathiafulvalene and sandwiched transition metal bis(dicarbollide) anions are of great interest in the development of new molecular conducting materials. The data on their synthesis, crystal structure, and electrical and magnetic properties were reviewed. The effect of various substituents in the metallacarborane anion on the structure and physical properties of their tetrathiafulvalene-based radical cation salts was analyzed. Relationships between the crystal structure and properties of the tetrathiafulvalene-based radical cation salts containing sandwiched transition metal bis(1,2-dicarbollide) anions are discussed.
