  Synthesis, characterization, photoluminescent properties and supramolecular aggregations in diimine chelated cadmium dihalides

  摘要：

  A series of 12 new cadmium compounds, [Cd(X-2)(L)] (4, 10), [Cd(X-2)(L)(DMSO)] (9), [Cd(X-2)(L)](2) (1-3, 5, 7, 8, 11, and 12), and [Cd(Cl-2)(2)(L)](n) (6) where X=chloride, bromide, and iodide, and diimine L=(E)-N-(pyridin-2-ylmethylidene)arylamine, were synthesized and characterized by elemental analyses. The spectroscopic properties were investigated by IR, UV-Vis, fluorescence, and H-1 NMR studies. The solid-state structures of the 12 reaction products were studied by X-ray crystallography. A majority of the structures are binuclear with five-coordinate cadmium centers: dimerization occurs through mu(2)-bridging of the respective halides; the second halide is bound terminally. In the case of X=Br and I, dimerization is circumvented when L carries an additional donor capable of coordinating cadmium (4, 10) or when the additional donor is provided by coordinating solvent (9). A similar situation pertains in the CdCl2 analog (7). In the case where L strongly coordinates with cadmium, i.e. (6), an edge-shared polymeric chain and octahedrally coordinated cadmium are found as a result of mu(2)-bridging of both chloro ligands. An interesting feature of the crystal packing is the observation of rare C-H pi interactions where the pi-system is a chelate ring or a Cd2Br2 unit.
