Wheatley, P. J. published the artcileCrystallography of some cyanine dyes, Product Details of C2H8Cl2N4S2, the publication is Journal of the Chemical Society (1959), 3245-50, database is CAplus.
The cell constants and space groups of some cyanine dyes and their solvates were determined The structure of the unsolvated dye 3,3′-diethylthiacarbocyanine bromide was elucidated from 2 projections. The cation is planar with the conjugated chain in the extended form. The S atoms are cis with respect to this chain. Some curious properties of the crystals are described. The results of the structure determination are correlated with other properties of cyanine dyes.
