| 摘 要： | The title complexes crystallize in space groups C(?)-P(?) and C_(2h)~5-P2_1/c, and with unit cell parameters a=8.488. b=10.100, c=11.974. α=72.73°, β=78.56°, γ=73.55°, and a=11.496, b=9.883. c=16.360, β=100.18°, respectively. All the V coordinates are obtained from Patterson and direct methods, respectively, and then Fourier and difference Fourier methods are employed to deduce other non-hydrogen atoms. Structural parameters are refined with least-squares technic, yielding final discrepancy factors R=0.081 and 0.067, respectively. Structural analyses demonstrate that the dimer of VO_2~+ complex is formed through the sixth-position bonding of a bridge oxygen atom of one VO_2~+ group with another VO_2~+, and the formation of VO(O_2)(C_(15)H_(10)N_3O)(C_5H_5N) shows that VO~(2+) complex with strong chelating tridentate PAN-seems less difficult to transform into the pentagonal bipyramid VO~(3+) complex. Since no peroxo species has been used in the synthesis, the fact that a peroxo group forms in the
