Solvothermal reactions of MnCl_2·4H_2O with(pyridin-2-yl)methyl 4-(2-(4-((pyridin-2-yl)methoxy)phenyl)diazenyl)benzoate(L1) via an in situ ligand transformation reaction produced a new coordination polymer, {[Mn_... Solvothermal reactions of MnCl_2·4H_2O with(pyridin-2-yl)methyl 4-(2-(4-((pyridin-2-yl)methoxy)phenyl)diazenyl)benzoate(L1) via an in situ ligand transformation reaction produced a new coordination polymer, {[Mn_(2.5)Cl_3L_2(H_2O)]·H_2O}_n(1, where HL = 4-(2-(4-((pyridin-2-yl)methoxy)phenyl)diazenyl)benzoic acid). The L1 ligand was decomposed in situ to L^- which was coordinated with Mn(Ⅱ) to form compound 1 in the solvothermal synthesis process. Complex 1 was characterized by IR spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction.Compound 1 possesses a 2D network. In addition, stability and photoluminescent property of 1 were also investigated. 展开更多

Two new complexes based on 6-hydroxypicolinic acid(H_2picO) and 1,10-phenanthroline(phen), such as [Cu_4(picO)_4(phen)_4]·12 H_2O(1) and {[Cd_4(picO)_4(phen)_4(H_2O)_2]·5H_2O}_n(2), have been synthesized and... Two new complexes based on 6-hydroxypicolinic acid(H_2picO) and 1,10-phenanthroline(phen), such as [Cu_4(picO)_4(phen)_4]·12 H_2O(1) and {[Cd_4(picO)_4(phen)_4(H_2O)_2]·5H_2O}_n(2), have been synthesized and characterized by IR, elemental analyses, thermogravimetric analyses and X-ray diffraction technique. Single-crystal X-ray diffraction analyses revealed that the two complexes both crystallize in the triclinic system, space group P(16)-. For complex 1, the picO ligands adopt a tridentate coordination mode to link copper(Ⅱ) ions into dimmers. PicO ligands also adopt a tridentate mode in complex 2, which connects the cadmium(Ⅱ) to form a one-dimensional chain. Moreover, luminescent properties of 1 and 2 were also investigated. 展开更多
