In the first part of project B7, targeting high oxidation states of the transition metals, NASICON type phosphates Na3Cr2(PO4)3, NaCrMV(PO4)3, NaMnIIIMV(PO4)3, and NaFeIIIMV(PO4)3 (M: Nb, Ta) will be syn-thesized and characterized with respect to their de-intercalation behavior. Oxidative coupling of phos-phate anions in Ag3CrIII(PO4)2, Ag3CrIII3(PO4)4, and Ag9CrIII3(P2O7)3(PO4)2 to "AgCrIIIP2O7", "Ag2CrIII6(P2O7)2(PO4)4", and "AgCrIII3(PO3)6(P2O7)" will be studied. In the second part of project B7 the kinetically controlled reduction of metalyl groups (M=O)n+ in solids phosphates (alphaII-VVOPO4, (Mo-VIO2)2P2O7, WVI2O3(PO4)2, WVIOP2O7) and its significance for C-H activation will be investigated besides redox equilibria in systems VVOPO4-MoVOPO4 and WVOPO4-MoVOPO4.

在B7项目的第一部分，针对过渡金属的高氧化态，合成了Na3Cr2(PO4)3、NaCrMV(PO4)3、NaMnIIIMV(PO4)3和NaFeIIIMV(PO4)3(M：Nb，Ta)的NASICON型磷酸盐，并对它们的脱嵌行为进行了表征。研究了Ag3CrIII(PO4)2、Ag3CrIII3(PO4)4和Ag9CrIII3(P2O7)3(PO4)2中的磷酸盐阴离子氧化偶联成“AgCrIIIP2O7”、“Ag2CrIII6(P2O7)2(PO4)4”和“AgCrIII3(PO3)6(P2O7)”。在B7项目的第二部分，除了研究VVOPO4-MoVOPO4和WVOPO4-MoVOPO4体系的氧化还原平衡外，还将研究固体磷酸盐(AlphaII-VVOPO4，(Mo-VIO2)2P2O7，WVI2O3(PO4)2，WVIOP2O7)中金属基团(M=O)n+的动力学控制还原及其对C-H活化的意义。
