Abstract

This paper reports the synthesis, crystal structures and conducting properties of the first BEDT-TTF radical-cation salts with D3 symmetry tris-coordinated racemic lanthanide(III) anions. It is also the first crystallographic determination of the nine-coordinate tris(chelidonato)terbate and tris(chelidonato)dysprosate anions (chelidonic acid = clo = 4-oxo-4H-pyran-2,6-dicarboxylic acid). Salt α-(BEDT-TTF)5M(chelidonato)3·EtOH·2H2O is semimetallic for M = Tb, and semiconducting for M = Dy. These conducting properties are consistent with the band structure for both salts.
