新型手性金属-有机配位聚合物的合成、结构与性质

Abstract

Two new homochiral metal-organic coordination polymers[M(D-cam) (H(2)mbdpz)](n)[M =Zn(complex 1), Co(complex 2); D-H(2)cam = D-(+)-camphoric acid, H(2)mbdpz = 4, 4'-methylenebis (3, 5-dimethylpyrazole)] were prepared by mixing ligands with corresponding transition metal ions under hydrothermal conditions. The complexes were characterized by means of single-crystal X-ray diffraction, elemental analysis, thermograrimetri analysis(TGA), powder X-ray diffraction(XRD) and photoluminescent(PL) spectrometry. X-ray crystallography reveals that complexes 1 and 2 are isomorphous and homochiral, exhibiting the three-dimensional open structure with a ThSi2 type of uninodal 3-connected networks.
