Abstract:
In this paper, two new coordination polymers were synthesized by solvothermal method. At the same time, the reaction process of solvothermal method, influencing factors such as molar ratio of reactants, pH value, temperature and so on are discussed, and the best experimental conditions are determined. The coordination properties of the central metal ions and ligands are summarized. The conductivity of the Crystal was measured by UV-Vis-NIR diffuse reflectance spectroscopy,[NiCl2(bpp)2]n energy gap value is 2.7ev, which belongs to semiconductor;[(bpp) the energy gap value of 3 Mo5P2O23]· 8H2O is 1.8ev, which belongs to semiconductor. Thermogravimetric analysis showed that [NiCl2(bpp)2]n could exist stably at 203.8 ℃, and [(bpp)3 Mo5P2O23]· 8H2O could exist stably at 207 ℃.

Abstract:
with chiral ligand ()-N-p-Toluenesulfonyl-L-glutamic acid (H2tsgluO) and 1,3-(4-pyridyl) propane (bpp) A chiral complex {Ag(HtsgluO)(bpp)}n(1) was synthesized with silver salt and characterized. X-ray diffraction showed that the complex was monoclinic, P21 Space Group, a = 1.220 79(18)nm, B = 1.034 49(16)nm,c = 2.059 5(3)nm,β = 96.006(2)°,V = 2.586 7(7)nm3,Z = 4,R1=0.060 2, silver ions in a distorted tetrahedral coordination environment, respectively, with 1 HtsgluO-oxygen atoms, 2 bpp nitrogen atoms and 1 silver ion coordination. The complex formed a two-dimensional layered structure through Silver-Silver bonds, and further formed a three-dimensional supramolecular structure through hydrogen bonds. In addition, the thermogravimetric and fluorescence properties of the complexes were studied.
