摘要：
The new binuclear molybdenum(V) complex Na-4[Mo2O4(HNTA)(2)](2)center dot 19H(2)O (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) angstrom, V = 5645.58(16) angstrom(3), Z = 4, C24H66Mo4N4Na4O51, M-r = 1702.50, D-c = 1.958 g/cm(3), mu = 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 > 2(sigma I)). Each Mo-V 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.
