The Coordination Behavior of Two New Complexes, [(CHNO)CdCl](I) and [(CHNO)CuCl] (II), Based on 2,6-Dimethanolpyridine; Elaboration of the Structure and Hirshfeld Surface, Optical, Spectroscopic and Thermal Analysis.

Two novel complexes, [(CHNO)CdCl](I) and [(CHNO)CuCl],havebeen synthesized and characterized. Single crystal X-ray diffraction revealed that in compound (I), 2,6-dimethanol pyridinium acts as a monodentate ligand through the O atom of the hydroxyl group. Contrarily, the 2,6-dimethanol pyridine ligand interacts tridentately with the Cu(II) ion via the nitrogen atoms and the two oxygen (O, O') atoms of the two hydroxyl groups.
