Abstract:
A novel compound, (4,4′-Hbpy)3[NaMo8O 26](4,4′-bpy)2(H2O)4 1 (bpy = bipydine), was synthesized by the hydrothermal method. Single-crystal X-ray diffraction shows that compound 1 belongs to the monoclinic system, space group C2/m with a = 19.1921(5), b = 18.6931(6), c = 9.3821(3) Å, β = 104.8020(11)°, V = 3254.22(17) Å3, C50H 51Mo8N10NaO30, Mr = 2062.52, Z = 2, F(000) = 2016, μ = 1.591 mm-1 and Dc = 2.105 g/cm3. The final R = 0.0283 and wR = 0.0912 for 3118 observed reflections (I > 2σ(I)). Compound 1 contains the β-[Mo 8O26]4- anion, sodium ion, 4,4′-bpy and lattice crystalline water molecules. The β-[Mo8O26] units link the sodium ion to form a chain structure. The infinite chains of [Na(Mo8O26)]3- blocks are surrounded by protonized 4,4′-bpy cations, 4,4′-bpy and lattice crystalline water molecules. The 2D-IR correlation spectroscopy study indicates that the stretching vibrations of Mo=O occur more preferentially due to the thermal effect. The TGA analysis shows that compound 1 has high thermal stability.
