Syntheses, Crystal Structure and Luminescent Properties of a Novel Mn(II) Coordination Polymer Based on 1,3,5-Benzenetricarboxylic Acid

Coordination polymers are a novel class of crystalline materials, which have attracted a huge amount of interest in recent decades. We selected an organic ligand 1,3,5-benzenetricarboxylic acid (H3BTC) to assemble with Mn(II) ions to construct a novel Mn(II) coordination polymer crystal material (namely complex 1). The resultant sample was successfully synthesized under the solvothermal reaction. Complex 1 possesses a three-dimensional (3D) framework based on two different Mn(II) clusters: [Mn-4(COO)(8)] and [Mn-2(COO4)]. Furthermore, the resultant sample can be characterized in detail by powder X-ray diffraction (PXRD), Fourier-transform infrared spectra (FT-IR), thermal gravimetric analyses (TGA), elemental analysis (C, H and N) and luminescence.
