Molecular and Crystal Structures of Dicationic Tetrakis(1,3-benzodithiol-2-ylidene)cyclopentanone

Abstract

Molecular and crystal structures of dicationic tetrakis(1,3-benzodithiol-2-ylidene)cyclopentanone (1b), (1b2+)2(ReO4−)4(CH3CN)3(H2O)0.7, were successfully determined by X-ray single-crystal diffraction. It was suggested that two 1,3-dithiol-2-ylidenes adjacent to the carbonyl group were effectively conjugated with each other. The remaining two 1,3-dithiol-2-ylidenes, where two positive charges were mainly distributed, were considerably twisted from the central five-membered ring.
