Solvothermal Syntheses, Structures And Physical Properties Of Coordination Compounds Constructed From 4-[(Carboxymethyl)thio]-Benzoic Acid

In recent years, coordination polymers as a novel functional material develop rapidly and become a hot topic in the field of materials chemistry. Coordination polymers have evoked increasing interest, mainly due to their potential applications in optical,electronic, magnetic, adsorption, catalysis, gas storage, molecular recognition, and etc..A large number of functional coordination polymers have been designed and synthesized through choosing functional organic ligands and metal ions. Among various organic ligands, carboxylic acid ligands have been extensively used as multifunctional linkers, because of their flexible coordination features and a variety of coordination modes. In this article, we selected ligands with different configurations to construct six metal-organic coordination compounds. These results will be introduced from the following issues:1. Two novel Pb and Cd metal-organic complexes, [Pb(CMTB)·H2O]n(1) and[Cd(CMTB)]n(2)(CMTB = 4-[(carboxymethyl)thio]-benzoic acid), have been successfully assembled in the same experiment situation. They were characterized by single crystal X-ray diffraction, IR spectroscopy. The luminescent and thermal properties of compounds have been investigated.2. Four novel metal-organic complexes, Zn(CMTB)(bipy)]·(H2O)2(3), [Cd(CMTB)(bipy)]·(H2O)1.25(4), {[Cd(CMTB)(phen)]2·3H2O}n(5) and [Zn(Imidazole)2]n(6), have been prepared and structurally characterized with adjusting the roles of different organic nitrogen heterocyclic compounds such as bipy, phen and imidazole. They were characterized by single crystal X-ray diffraction, IR spectroscopy. The luminescent and thermal properties of compounds have been investigated.
