The charge transfer complex N,N-dimethylbenzylamine which is between the molybdosilicic acid and organic substrate has been prepared. Yellow crystals of the title compound ([(CH3)2NH(CH2)C6H5]4SiMo12O40·2CH3CN·H2O) were synthesized from the mixture of water and acetonitrile. The single-crystal X-ray analysis reveals that the crystal crystallizes in triclinic system, space group P1 with a = 13.313(2), b = 14.673(2), c = 19.736(3)A,α= 86.22(1),β= 88.76(1),γ= 66.97(1)0, V = 3540.2(9) A3 and Z = 2. The anion has the Keggin structure. The Mo-O bond distances range from 1.675(3) to 1.691(3) A for the terminal oxygen atoms, 1.798(3) to 2.045(3)A for the bridging ones, and 2.328(3) to 2.361(3)A for those in the SiO4 tetrahedron. The Si-O bond distances fall in the range of 1.623(3)～1.630(3)A.
