X-ray single crystal analysis reveals FJ-10 belongs to a triclinic crystal system, space group P-1, a=1.038 18(6) nm, b= 1.230 41(7) nm, c=1.234 81(7) nm, α=97.207 0(10)°, β=109.411 0(10)°, γ=113.081 0(10)°, V=1.307 79(13) nm 3, R 1=0.039 9, wR 2=0.101 3. The topology structure of FJ-10′s framework is characterized by PO 3(OH) bridged 4-rings. FJ-10 exemplifies firstly the π-π stacking of hybrid chains whose structure-building units are involved in ZnO 3N 2. FJ-10 predicts the novel hybrid transition phosphates.展开更多
A hydrothermal reaction of NaVO3, Ce(NO3)3, H3BO3, 2,2′ bipyridine and water in a molar of 1∶2∶3∶2∶333 gives a yellow crystal [(C10H8N2)2VO2](H2BO3)·3H2O.

It crystallizes in a triclinic with space group and unit cell parameters a=0.6643(1)nm, b=1.1794(2)nm, c=1.4822(3)nm, α=101.39(3)°, β=101.59(3)°, γ=97.15(3)°, Z=2, Dc=1.542g·cm-3, μ=0.508mm-1, F(000)=528, R1=0.0736, wR2=0.1998,Goof=1.071. X ray crystallographic study showed that the VN4O2 octahedron unit is distorted, in which the V1 atom is coordinated by two terminal O1 and O2 atoms, and N1, N2, N3 and N4 atoms from two 2,2′ bipy ligands. The hydrogen bonding are observed between 2,2′ bipy and adjacent terminal oxygen atom. It is noteworthy that π πstacking interaction between adjacent 2,2′ bipy groups plays an significant role in stabilization of the structure of crystal. CCDC: 194327.展开更多

The structure is characterized by the co-existence of octahedral [Fe(2,2?bipy)3]2+ cations and b-octamolybdate [Mo8O26]4- anions.
