## Abstract The structure of the bis‐dimethyl trimethine cyanine perchlorate crystallizes in the space group Cc with the lattice constants __a__ = 7,873 Å, __b__ = 19.01 Å, __c__ = 7.735 Å, β = 103.36°. It was spatially and anisotropically refined to a discrepancy factor of 0.09. The CC distances
## Abstract Bis‐dimethyl pentamethine cyanine perchlorate crystallizes in the space group __P__(2~1~/__c__) with the lattice constants __a__ = 6.230 Å; __b__ = 14.970 Å; __c__ = 14.005 Å; β = 83.54°. The carboncarbon bonds show the bond length compensation, typical of polymethines, towards a parti
