【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.更多还原

【Abstract】 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 condition1 and condition2.更多还原
