摘要
New polymeric cadmium complexes, alpha-[CdLCl2](n) (1), [CdL2Cl2](n) (2) and beta-[CdLCl2](n) (3) (L = 4-amino-2,1,3-benzothiadiazole), were obtained as products of the reaction of CdCl2 with L. The synthetic procedures allowing isolation of pure 1-3 were optimized. The structures of 1-3 were established by single-crystal X-ray diffraction and the compounds were characterized by UV-Vis and IR spectroscopy. In these compounds, L is either mu-bridging (1) or terminal (2 and 3). The UV-Vis spectra of the complexes in the solid state resemble that of free L. However, coordination of L leads to a significant shift of emission in photoluminescence spectra from yellow (free L to red (1-3). [GRAPHICS] .
