The novel cobalt(II) complex, trans-dipyridinebis(3-acetyl-2-oxo-2H-chromen-4-olato)cobalt(II), was synthesized in ethanol. The coordination sphere of the cobalt cation was elucidated using single-crystal X-ray diffraction analysis and spectroscopic techniques (FT-IR, UV-Visible and fluorescence). Hirshfeld surface analysis indicates that hydrogen bond interactions, such as C–H•••O hydrogen bonding between the oxygen of lactone group and the pyridine appear as a primary interaction between the complex’s molecules. The metal-ligand coordination strongly influences the fluorescence intensity (the fluorescence quenching) and the offset of the emission wavelength. The metal complex was monitored for antimicrobial activity using the disk diffusion method and showed significant activity compared to the coumarin ligand.
