Abstract

Four new structures of Cd ^II complexes containing bis(2-pyridylmethyl)amine (bispicam) ligands have been determined. Chloride anions bridge two Cd ^II ions to form a dinuclear complex [(Cd(bispicam)Cl) ₂(μ ₂-Cl ₂)] (1), and bromide and iodide ions produce two halide-coordinated [Cd(bispicam)X ₂] complexes (X = Cl for 2 and Br for 3). Nitrate anions produce both nitrate-coordinated [Cd(bispicam) ₂(NO ₃)] ⁺ and simple [mer-Cd(bispicam) ₂] ²⁺ with three nitrate counter-anions (4). These results indicate that anion effects play very important roles for construction of crystal structures and geometrical isomerism. Moreover, the homogeneous catalyst [Cd(bispicam) ₂] (ClO ₄) ₂ (5) catalyzed efficiently the transesterification of a variety of esters with methanol, while rest of the complexes have displayed very slow conversions. Furthermore, 1-5 showed the intense emissions at room temperature, which could be used as a good candidate for a potential hybrid inorganic-organic photoactive material.
