Structural characterization and Hirshfeld surface analysis of a Co∥ complex with imidazo[1,2-a]pyridine

A new mononuclear tetrahedral Co-parallel to complex, dichloridobis(imidazo[1,2-a]pyridine-KNi)cobalt(II), [CoCl2(C7H6N2)(2)], has been synthesized using a bioactive imidazopyridine ligand. X-ray crystallography reveals that the solidstate structure of the title complex exhibits both C H center dot center dot center dot Cl and pi-pi stacking interactions in building supramolecular assemblies. Indeed, the molecules are linked by C-H center dot center dot center dot Cl interactions into a two-dimensional framework, with finite zero -dimensional dimeric units as building blocks, whereas pi-pi stacking plays a crucial role in building a supramolecular layered network. An exhaustive investigation of the diverse intermolecular interactions via Hirshfeld surface analysis enables contributions to the crystal packing of the title complex to be quantified. The fingerprint plots associated with the Hirshfeld surface clearly display each significant interaction involved in the structure, by quantifying them in an effective visual manner.
