主　　题：crystal structure V-O tetrahedron 1,10-phenanthroline 

摘      要：[Zr（phen）4（H2O）4O2（V4O12）]（phen）2 1 （phen = 1,10-phenanthroline） was synthesized under hydrothermal condition. The crystal of 1 belongs to triclinic, space group P1^- with a = 10.6334（8）, b = 11.9201（8）, c = 14.6505（10） A, α = 69.9980（10）, β = 84.9240（10）, γ = 84-1300（10）°, V = 1733.0（2） A^3, Z = 1, Mr = 1672.27, Dc = 1.602 g/cm^3, C72H56N12O18V4Zr, F（000） = 848, μ（MoKa） = 0.747 mm^-1, S = 0.957, R = 0.0504 and wR = 0.1173 for 4011 observed reflections （1 〉 20（I））. The crystal structure of 1 could be discussed in terms of {Zr（phen）2（H2O）2O2}, un-coordinated 1,10-phenanthroline molecules and { V4O12 } unit. In { Zr（phen）2（H2O）2O2 }, the coordination geometry of zirconium is a dodecahedron, but {V4O12} unit is constructed from four apex-sharing {VO4} tetrahedra. Furthermore, {V4O12} links with two {Zr（phen）2（H2O）2O2} units via two bridging oxygen atoms. Interestingly, the two {Zr（phen）2（H2O）2O2} units display D- and L-enantiomers, respectively, upon which the whole molecule represents a racemoid configuration.
