The polyoxoanion incorporated {Mn（CO）3^＋} complex, （n-Bu4N）2[Mo6O16（OCH3）2{HOCH2C（CH2O）3}2·{Mn（CO）3}2]（1）, has been synthesized by the reaction of （n-Bu4N）4[Mo8O26] with Mn（CO）5Br in methanol, in the presence of C（CH2OH）4. The complex 1 has been characterized by IR, UV-Vis, X-ray single crystal diffraction, and TG. Crystal data for the complex 1：C25H48MnMo3NO16 （1）, Triclinic Pi, a=0.9405（3） nm, b=1.3351（4） nm, c=1.5455（4） nm, α=103.206（5）°, β=102.165（5）°, γ=100.784（5）°, V=1.7896（9） nm^3, Z=2, R1=0.0703, wR2= 0.1495. The structure analysis of complex 1 shows that the complex consists of two tetrabutylammonium cations and a polyoxomolybdate anion that incorporates two fac-Mn（CO）3^＋ units. The anion of complex 1 can be considered as the dimer of two rhomb-like anions by sharing of two comers.
