摘要 目的通过调节[Ni(II)(Dipha)(Benzidine)]体系的pH值和改变L-(L-=Cl-,NO3-),研究其在水热条件下对晶体生长的成晶条件。方法通过水热法合成该体系的系列晶体。结果实验表明,水热法合成该体系的系列晶体,pH≈7.0,镍盐(NiL2)选用NiCl2或Ni(NO3)2有利于配合物晶体的形成。结论对于该体系溶液pH≈7.0和选择合适的酸根阴离子盐来提供金属离子有利于配合物晶体的形成。 Aim To study the influences of pH values in solusion and anionic L^- (L^Cl^- ,NO3^-) to the crystal growing of [ Ni(Ⅱ) (Dipha) ( Benzidine ) ]) under hydrothermal conditions. Methods The hydrothermal method is used to synthesize [ Ni(Ⅱ) (Dipha) ( Benzidine ) ] and prepare its crystal. Results The experimental trsults shown that optimum conditions of the crystal growing are pH ≈7.0, Ni salts are either NiCl2 or Ni(NO3)2 to easly produce coordation crystal, A series crystals were synthesized by the hydrothermal method. Conclusion In this system,[ Ni(Ⅱ) (Dipha) ( Benzidine ) ], ph≈7 and a appropriate L^- are all necessary conditions for crystal formation and growth.
