First molecular conductors of BPDT-TTF with metallacarborane anions: (BPDT-TTF)[3,3′-Сr(1,2-C2B9H11)2] and (BPDT-TTF)[3,3′-Сo(1,2-C2B9H11)2] – Synthesis, structure, properties

Abstract The first molecular conductors based on bis(1,3-propylenedithio)tetrathiafulvalene and transition metal bis(dicarbollides) (BPDT-TTF)[3,3′-Сr(1,2-C 2 B 9 H 11 ) 2 ] ( 1 ) and (BPDT-TTF)[3,3′-Сo(1,2-C 2 B 9 H 11 ) 2 ] ( 2 ) were synthesized and their crystal structures were determined by X-ray analysis. The electric conductivity measurements revealed that these compounds are semiconductors at room temperature.
