摘要

Two tetra-Co^II substituted sandwich-type polyoxotungstate, H₃[Co(en)₂]_0.5[Co(en)₂(H₂O)]₂[Co(en)(H₂O)]₂[Co₄(en)(B-α-SiW₉O₃₄)₂]·9H₂O (1, en = ethylenediamine) and [Co(mea)₂(2,2′-pby)]₂[Co₄(Hppz)₂(B-α-PW₉O₃₄)₂]·2H₂ppz·8H₂O (2, mea = monoethanolamine, 2,2′-bpy = 2,2′-bipyridine, ppz = piperazine), have been synthesized under hydrothermal conditions and characterized by IR spectroscopy, UV spectroscopy, TG, powder XRD and single-crystal X-ray structural analysis, respectively. Compound 1 exhibits a layer, in which the en molecules and [Co(en)₂]²⁺ cations as the linkers connect [Co₄(B-α-SiW₉O₃₄)₂]¹²⁻ clusters to form the layer. Compound 2 shows a supramolecular layer built by [Co₄(Hppz)₂(B-α-PW₉O₃₄)₂]⁸⁻ cluster units via N–H···O H-bond interactions, in which three types of organic amine ligands are included.
