Synthesis and Structural Characterization of Manganese Carbonyl Incorporated Polyoxomolybdate (n-Bu_4N)_2[Mo_6O_(16)(OCH_3)_2{HOCH_2C(CH_2O)_3}_2{Mn(CO)_3}_2]

The polyoxoanion incorporated {Mn(CO)3+} complex,(n-Bu4N)2Mo6O16(OCH3)2{HOCH2C(CH2O)3}2{Mn(CO)3}2](1),has been synthesized by the reaction of (n-Bu4N)4MosO26] with Mn(CO)sBr 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 P1,a=0.9405(3) nm,b=1.3351 (4) nm,c=1.5455(4) nm,a=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 comers.
