Abstract

Cd(II) halide complexes [Cd<sub>2</sub>X<sub>4</sub>(tpa)<sub>2</sub>] (<strong>1</strong>: X = Cl, <strong>2</strong>: X = Br, <strong>3</strong>: X = I; tpa = tris(2-pyridyl)amine) have been synthesized. X-Ray diffraction analyses of <strong>2</strong> and <strong>3</strong> reveal their asymmetrical dinuclear structures: one Cd(II) atom is octahedrally coordinated to four N atoms of two tpa ligands and two bridging halides; the other Cd(II) is tetrahedrally coordinated to two terminal (X<sub>(t)</sub>) and two bridging (X<sub>(b)</sub>) halides. By multiple intra- and intermolecular π-π interactions between the tpa pyridine rings, the ligands of <strong>2</strong> and <strong>3</strong> are linked to form a 2D network and 1D linear structures, respectively. In the Raman and far-infrared spectra, the absorption bands due to Cd-X<sub>(b)</sub> stretching modes lie at lower wavenumbers compared to the Cd-X<sub>(t)</sub> stretches. It can be inferred from the spectroscopic data that <strong>1</strong> has a dinuclear structure similar to those of <strong>2</strong> and <strong>3</strong>. <p>
