Abstract

The reaction of the aryl-oxide ligand H 2L [H 2L = N,N-bis(3, 5-dimethyl-2-hydroxybenzyl)-N-(2-pyridylmethyl)amine] with CuSO 4·5H 2O, CuCl 2·2H 2O, CuBr 2, CdCl 2·2.5H 2O, and Cd(OAc) 2·2H 2O, respectively, under hydrothermal conditions gave the complexes [Cu(H 2L 1) 2]·SO 4·3CH 3OH (1), [Cu 2(H 2L 2) 2Cl 4] (2), [Cu 2(H 2L 2) 2Br 4] (3), [Cd 2(HL) 2Cl 2] (4), and [Cd 2(L) 2(CH 3COOH) 2]·H 2L (5), where H 2L 1 [H 2L 1 = 2, 4-dimethyl-6- ((pyridin-2-ylmethylamino)methyl)phenol] and H 2L 2 [H 2L 2 = 2-(2, 4-dimethyl-6-((pyridin-2-ylmethylamino)methyl) phenoxy)-4, 6-dimethylphenol] were derived from the solvothermal in situ metal/ligand reactions. These complexes were characterized by IR spectroscopy, elementary analysis, and X-ray diffraction. A low-temperature magnetic susceptibility measurement for the solid sample of 2 revealed antiferromagnetic interactions between two central copper(II) atoms. The emission property studies for complexes 4 and 5 indicated strong luminescence emission.
