Hydrothermal Synthesis, Crystal Structure and Luminescence Property of a 2D Manganese(II) Coordination Polymer

Solvothermal reactions of MnCl2 center dot 4H(2)O 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, {[Mn2.5Cl3L2(H2O)]center dot H2O}(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.
