Synthesis, structure, and luminescent property of a new Cd(II) coordination polymer with (4, 8)-connected topology

Via the solvothermal reactions of Cd(NO3)2 and H2L, a new Cd(II) compound, namely [Cd(L)]n (1 H2L = 5-CH2OH-isophthalic acid), was obtained. This compound was further characterized by single-crystal X-ray diffraction analysis, elemental analyses, and powder X-ray diffraction analyses. Single-crystal X-ray diffraction analysis reveals that compound 1 features a 3D framework based on dinuclear [Cd2(COO)2] subunits. Topological analysis reveals that compound 1 represents a new (4, 8)-connected topology. In addition, the luminescent property of 1 was also investigated at room temperature.
