Complexes of Cu(II) and Ni(II) with N-salicylideneaminopyridinium iodide, which have not been previously described, have been synthesized. By physicochemical methods it is shown that the complexes are chelate with the composition 1:2 (of metal and aldehyde residue of ligands deprotonized at ...

Photochemical and thermal trans/cis isomerization reactions are reported for 1-methyl-4′-(p-N,N dimethyl-amino styryl) pyridinium iodide, Cy, which is synthesized in the trans configuration. In a basic solution the trans form, Cy tr, cannot isomerise directly to the cis form. Its protonated...
