Synthesis, Characterization and Structure of a New Partially-sulfided Ni-Mo Dimetallic Complex and Its Evaluation as a Catalyst Precursor for Dibenzothiophene Hydrodesulfurization
摘要:
A new complex, [Ni(H2O)6][Mo2O2S2(edta)]·2H2O (1, edta=ethylenediaminetetraacetate), which was partially-sulfided, was synthesized and characterized by single-crystal X-ray diffraction. Compound 1 belongs to the monoclinic system, C2/c space group with a=7.1844(2), b=12.5626(4), c=27.0201(8) Å, β=93.066(3)°, V=2435.21(14) Å3, C10H28S2Mo2N2NiO18, Mr=779.02, Dc=2.1247 g/cm3, μ(MoKα)=2.035 mm-1, F(000)=1550, Z=4, the final R=0.0366 and wR=0.0656 for 5359 observed reflections (I>2σ(I)). There are one isolated [Ni(H2O)6]2+ cation and one [Mo2O2S2(edta)]2- anion in its asymmetric unit, and they are connected through multiple hydrogen bonds to generate a 3D network. In addition, the thermal behavior of compound 1 and the hydrodesulfurization activity of the catalyst derived from compound 1 were studied.
