Abstract: A novel compound [(CH3CH2)4N]4[(La12(OH)12MoO29)] was synthesized by hydrothermal reaction. The single crystal X-ray diffraction shows that the compound crystallized in the monoclinic space group C2/c; a=2.5729(4) nm, b=1.4318(1) nm, c=2.1217(4) nm, β=111.56(1)°, V=6.8235(7) nm3, Z=4, R=0.0751. The basic building blocks of the crystal structure included one MoO5 hexahedron and twelve LaO6 octahedra which shared a common edge to form a [(La12(OH)12MoO29)]4- unit. These units were held together by the [(CH3CH2)4N]+ ions.
