A novel compound [(CH 3CH 2) 4N] 4[(La 12 (OH) 12 MoO 29 )] 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) nm 3, Z =4, R =0 0751. The basic building blocks of the crystal structure included one MoO 5 hexahedron and twelve LaO 6 octahedra which shared a common edge to form a [(La 12 (OH) 12 MoO 29 )] 4- unit. These units were held together by the [(CH 3CH 2) 4N] + ions.
