Abstract

Five- and six-coordinate nickel complexes [(Dm-Pybox)NiCl2], [(Dm-Pybox)Ni(H2O)Cl2], [(Dm-Pybox)Ni(H2O)2Cl]Cl (2a), and [(Dm-Pybox)Ni(MeOH)2Cl]Cl (2b), where Dm-Pybox is 2,6-bis[4′,4′-dimethyloxazolin-2′-yl]pyridine, have been isolated and structurally characterized by single crystal X-ray diffraction. The solid state structures of 2a and 2b feature different modes of non-covalent interactions, C–H⋯Cl, C–H⋯O and O–H⋯Cl interactions. Spectroscopic and analytical methods, UV–vis and thermogravimetric analyses were done to further investigate chemical properties of the complexes.
