摘要
The new binuclear molybdenum(V) complex Na4[Mo2O4(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) ,V = 5645.58(16) 3,Z = 4,C24H66Mo4N4Na4O51,Mr = 1702.50,Dc = 1.958 g/cm3,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.
