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 P1, a=0.9405(3) nm, b=1.3351(4) nm, c=1.5455(4) nm, α=103.206(5)o, β=102.165(5)o, γ=100.784(5)o, 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.
A 1D zigzag polyoxometalate [(CH3)4N]1.50H3.50[Gd(GeW11O39)(H2O)2]·2.5H2O (1) was synthesized by reaction of the monovacant polyanion [α-GeW11O39]8-with Gd3+ ions in aqueous solution and characterized by IR, UV spectra, ICP, and X-ray crystallography. X-ray single-crystal structural analysis indicated that the title compound crystallized in a monoclinic lattice, C2/c space group with a=2.8201(5), b=2.2885(3), c=2.4033(4) nm, β=123.875 (2), V=12.878(4) nm3, Z=8, R1=0.0623, wR2=0.1287. The solid-state structure of the title compound displayed an infinite one-dimensional arrangement built up of [α-GeW11O39]8-polyanions connected by GdIII cations.
