A new one-dimensional CdII complex, [Cd(μ2-L)2]n (HL=3-(2-pyridyl)pyrazole) with planar [Cd(μ2-L)]2 unit: synthesis, crystal structure and emission property

A new one-dimension complex, [Cd(μ2-L)2]n (1, HL=3-(2-pyridyl)pyrazole), has been hydrothermally synthesized and characterized by elemental analysis, IR, TGA, and single-crystal X-ray diffraction analysis. In 1, the L ligand takes tridentate chelating-bridging coordination mode via deprotonation of the pyrazolyl NH group and coordination of the pyrazolyl N atom to a second metal ion. In the solid state, complex 1 shows blue photoluminescent property at room temperature.
