• The reaction of Co(OAc) 2 ·4H 2 O with multisite coordinated salamo-based ligand H 2 L containning six coordinating sites in presence of co-ligand NCS – anions afforded successfully a trinuclear Co(II) complex [Co 3 (L) 2 (NCS) 2 ]. The trinuclear Co(II) complex has been characterized by elemental analyses, UV-Vis, Fourier transform infrared spectroscopic methods and DFT calculation. In addition, the structure of the Co(II) complex has been confirmed by single crystal X-ray crystallography. X-ray crystal structure analysis of the Co(II) complex revealed that the Co(II) complex consists of three Co(II) atoms coordinated by two fully deprotonated ligand (L) 2– units and co-ligand NCS – anions. The close surveillance of the crystal structure of the Co(II) complex discloses some notable non-covalent interactions like H-bonding, C-H⋯π and π⋯π. The luminescent property of the Co(II) complex has been studied in methanol solution. Apart from, as a complementary revelation, intermolecular interactions with respect to percentages of hydrogen bondings in the X-ray crystal structure of the trinuclear Co(II) complex was quantified by analyses of Hirshfeld surfaces and fingerprint plots.
