【摘要】 基于{BiW₉}夹心化合物的研究已有报道,在抗肿瘤等方面具有广泛的应用[1,2]。我们利用溶液法合成了一种基于{BiW₉}的有机-无机杂化化合物,通过元素组成分析及TG确定其化学式为Na₄[{Co₄（H₂O）₂}₂(BiW₉O₃₃)₂]（H₂dmap）·10H₂O。×-射线单晶衍射仪分析表明,化合物属单斜晶系,C2/c空间群,a=43.399（17）A,b=18.242（7）A,c=17.078（7）A,α=90.00,β=103.322（5）,γ=90.00,V=13157（9）（12）A,Z=8。该结构是由两个三缺位的[BiW₉O₃₃]^9-阴离子通过包夹一个对称的菱形四核钴簇{Co₄（H₂O）₂}而形成,并通过四个钠离子相连形成一个二维平面,通过超分子作用、氢键与dmap配体形成三维结构。更多还原

【Abstract】 The sandwich compounds based on {BiWg} has been reported and has been widely application in the field of antitumor and so on.Syntheizing {BiWg} organic-inorganic heterocomplex modified by dmap ligands with an in-situ conventional solution synthesis method.The compound was characterized by elemental analysis and TG analysis,whose chemical formula is Na₄（H₂dmap）[{Co₄（H₂O）₂}₂(BiW₉O₃₃)₂]·10H₂O.The single-crystal X-ray diffraction analysis showed that the compound belongs to monoclinic crystal system,with space group of C2/c,a=43.399（17） A,b=18.242（7）A,c=17.078（7）A,α=90.00,β=103.322（5）,γ=90.00,V=13157（9）A,Z=8.The structure is built by two trivacant[β-B-BiW₉O₃₃]^9- moieties,which is joined together by four {Co₄（H₂O）₂} custers.The sandwich unit is connected with the four sodium ions to form a 2D plane.The 2D surfaces continue to be connected with the dmap ligands in a supramolecular interactions and the hydrogen bonding to further connect into a 3D network structure.更多还原
