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

They are fully characterized by FTIR、1H NMR、31P NMR、ESI-MS and EA. For the 6,7-dihydroxy coumarin, there was selective phosphorylation in the 6-hydroxyl group in the reaction. XRD analysis of 2f is described. The crystal is nomoclinic, space group P2(1)/n. there is hydrogen-bonding interaction between O atom on P=O and H atom on O-H.展开更多
