Synthesis and Structural Characterization of Manganese Carbonyl Incorporated Polyoxomolybdate (n-Bu4N)2[Mo6O16(OCH3)2{HOCH2C(CH2O)3}2{Mn(CO)3}2]

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 P. 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) nm3, 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 corners.
