Unprecedented preparation of dinuclear nickel(II) and zinc(II) complexes with Schiff base ligands transformation under solvolthermal conditions

Two novel centrosymmetric dinuclear nickel(II) and zinc(II) complexes were unprecedented prepared from mono-Schiff bases with salicylaldehyde derivatives and metal acetate under solvolthermal conditions. The mono-Schiff bases bearing 2-[(3-cyclohexylaminopropylimino)methyl]phenol backbones used to prepare nickel and zinc complexes can be transformed to other ligands in the reactions, which never occur under mild synthetic procedures.
