| Abstract: Two new alkaline earth metal coordination polymers[Ca (tdc)(DMF)2]n(1) and[Ba (tdc)]n(2)(H2tdc=2,5-thiophene dicarboxylate) have been synthesized under solvothermal condition.They were characterized by elemental analysis,IR spectroscopy,single crystal X-ray diffraction,powder X-ray diffraction,thermogravimetric analysis,and fluorescent analysis.Complex 1 exhibits a two-dimensional (2D) layer structure with a uninodal (4,4)-connected (44·62) topological type;whereas,complex 2 features a 3D framework consisting of elongated hexagonal channels.Solid-state photoluminescent properties indicate that complex 1 shows noticeable fluorescent emissions upon excitation in comparison to that of complex 2. |
