Description
Summary:Five- and six-coordinate nickel complexes [(Dm-Pybox)NiCl 2 ], [(Dm-Pybox)Ni(H 2 O)Cl 2 ], [(Dm-Pybox)Ni(H 2 O) 2 Cl]Cl (2a), and [(Dm-Pybox)Ni(MeOH) 2 Cl]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.
