ABSTRACT

The new cobalt(II) complex [Co(pydca)(bim)₃] (1) (where H₂pydca = pyridine-2,6-dicarboxylic, bim = benzimidazole) has been synthesized and characterized by elemental analysis, Infrared spectroscopy, X-ray single crystal analysis, thermogravimetric and fluorescent analysis. Single crystal X-ray diffraction analysis reveals that the mononuclear complexes are linked by N–H…O hydrogen bonds. Fluorescent analysis reveals that complex 1 exhibits intense luminescence in ethanol solution at room temperature.
