【摘要】 近年来,多酸基配合物因其在吸附、磁性、催化等方面具有潜在的应用价值而受到人们的广泛关注[1,2]。本文以一种柔性的双吡啶双酰胺N,N’-双(3-吡啶甲酰胺)-1,3-丙二胺(L)为配体在水热条件下合成了一个基于Anderson型多酸阴离子[TeMo6O24]6-(简写为TeMo6)的二维无机-有机配合物:[Cu3L2(TeMo6O24)(H2O)10]·2H2O。其晶体学数据如下:三斜晶系,P-1空间群,a=10.5020(4),b=12.9840(5),c=13.0880(5),α=118.1950 o,β=108.3480(10)o,γ=93.8660(10)o,V=1442.23(10)3,Z=1,F(000)=991,R1=0.0214,wR2=0.0561。在该结构中,四齿的TeMo6连接CuⅡ离子形成一维Cu-TeMo6链,双齿配位的L配体呈"V"字构型桥连相邻Cu-TeMo6链上的两个CuⅡ离子,形成了一种二维层结构。更多还原

【Abstract】 Recently,the design and synthesis of coordination complexes based on polyoxometalates(POMs) through crystal engineering have become an attracting research area,because of their potential applications in catalysis,absorption and magnetic materials [1,2].A new 2D inorganic-organic complex [Cu3L2(TeMo6O24)(H2O)10]·2H2O(L=N,N’-bis(3-pyridinecarboxamide)-1,3-propane) has been hydrothermally synthesized.The quadridentate [TeMo6O24]6-anions are coordinated with CuⅡ ions to form a 1D Cu-TeMo6 chain,and the bidentate L ligands with ‘V’-type configurations bridge the CuⅡ ions from the adjacent Cu-TeMo6 chains to construct a 2D layer structure.更多还原
