| 摘 要： | The new binuclear molybdenum（V） complex Na4Mo2O4（HNTA）2]2·19H2O （NTA = nitrilotriacetate） has been prepared and characterized by single-crystal X-ray diffraction analysis and IR. The crystal has space group Pnma with a = 10.2239（2）,b = 23.8174（3）,c = 23.1845（4） A,V = 5645.58（16）A^3,Z = 4,C24H66Mo4N4Na4O51,Mr = 1702.50,Dc = 1.958 g/cm^3,μ = 1.027 mm^-1,F（000） = 3280,T = 293（2） K,the final R = 0.0609 and wR = 0.1449 for 5512 observed reflections （I 〉 2σ（I））. Each MoV atom has a distorted octahedral coordination geometry,and the two coordination octahedra share a common edge to form a dioxo-bridged Mo2O4 unit which is coordinated by NTA ligands. The dianionic binuclear units Mo2O4（HNTA）2]^2- are interconnected by Na^＋ into a layered structure.
