Abstract: | Four dinuclear cadmium(II) complexes, [Cd2(L1)(μ2-Cl)Cl2] (1), [Cd2(L2)(μ2-Cl)Cl2] (2), [Cd2(L3)(μ2-Cl)Cl2] (3), and [Cd2(L4)3ClO4] (4), where HL1 = 4-methyl-2,6-bis(1-(2-piperidinoethyl)iminomethyl)-phenol, HL2 = 4-methyl-2,6-bis(1-(2-pyrrolidinoethyl)iminomethyl)-phenol, HL3 = 4-methyl-2,6-bis(1-(2-morpholinoethyl)iminomethyl)-phenol and HL4 = 4-methyl-2,6-bis(cyclohexylmethyl)iminomethyl)-phenol, were synthesized. They were characterized by elemental analysis, FT-IR, UV–Vis, fluorescence and electronspray ionization mass spectroscopy. Complexes 1 and 4 were also characterized by single crystal X-ray analysis. The cadmiums atoms in 1 are linked by μ2-chloride in a distorted square pyramidal geometry, whereas cadmium atom in 4 is in a distorted octahedral environment. The complexes show emission bands around 500 nm with excitation at 395 nm. |
