摘要
实验先用磷酸和钼酸盐合成磷钼杂多阴离子,再通过控制金属种类、pH值及温度,及与有机配体和物料比进行实验,最终制备出五钼二磷酸盐配合物(H2bpy)0.5{[Co(H2O)5][Co(Hb-py)(H2O)4][Mo5P2O23]},并通过IR和X-单晶衍射法进行表征,表征结果与现有文献记载相吻合.成功找到制备五钼二磷酸盐配合物的新条件:(1)温度为160℃左右,pH在4.2~4.5之间;或(2)温度为140℃,pH为3.1~3.5之间,反应3d,均可制备五钼二磷酸盐配合物.
Experimental synthesis only use phosphate and molybdate. By controlling the types of metal, PH value, temperature, organic ligand and experiments and material, the diphosphopentamolybdate (H2bpy)0.5{[Co(H2O)5][Co(Hbpy)(H2O)4][Mo5P2O23]} have been synthesized. It is characterized by IR and single crystal X-diffraction. The results are the same as that reported in literatures, Conditions: temperature is 140℃, pH is in range of 4. 2 - 4. 5. or Conditions:temperature is 140℃,pH is in range of 3. 1 - 3.5, three days. The diphosphopentamolybdate can be prepared under condition 1 and condition 2.
