Preparation, structures, and properties of nickel complexes containing 2,6-bis[4′,4′-dimethyloxazolin-2′-yl]pyridine, a pincer ligand
摘要:
Five- and six-coordinate nickel complexes [(Dm-Pybox)NiCl2], [(Dm-Pybox)Ni(H2O)Cl-2], [(Dm-Pybox)Ni(H2O)(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-HCl, C-HO and O-HCl interactions. Spectroscopic and analytical methods, UV-vis and thermogravimetric analyses were done to further investigate chemical properties of the complexes.
