The synthesis and characterization of four new solid dye complexes, CuL2(L= 2-[2-methoxy-5-(propane-1-sulfonyl)-phenyl azo]-naphthalen-1-ol, 5-{[3-(4,6-dihydroxy-[1,3,5]tri azine-2-ylamino)-phenyl]-hydrazones}-1-ethyl-4-methyl-2,6-dioxo-1,2,5,6-tetrahydro-pyridine-3-carboxylic acid diethylamide, 4-{bis-[4-(benzyl-ethyl-amino)-phenyl]-methyl}-phenol and 7-imino-4-methyl-7H-phenoxazine-1,3-diamine) is reported. The mode for ligand coordination has been determined by IR and EPR spectra. The carboxyl and amino group of dyes coordinates to the Cu(II) atom as a unidentate or as a chelating ligand.
