【摘要】 通过水热方法合成了2个夹心型磷钼簇基有机-无机杂化化合物(C4H14N3)(C4H15N3)4{Na[Mo6O15(H2PO4)4]2}.8H2O(化合物1)和{Ni[Mo6O15(H2PO4)4]2}(4,4′-bipy)3.H2O(化合物2,其中4,4′-bipy为4,4′-联吡啶),并对其进行元素分析、红外光谱和X射线单晶衍射表征.结构解析结果表明2个标题化合物均含有由2个{Mo6P4}簇和1个[MO6](M为Na,Ni)八面体通过共用顶点氧相连形成的中心对称的夹心型结构.化合物1中,具夹心结构的Na(P4Mo6)2与二乙烯三胺及水分子通过氢键连接形成超分子化合物;化合物2中,具夹心结构的Ni(2)[Mo6P4]2与质子化的4,4′-bipy通过氢键相连形成沿bc平面延伸的二维网络结构,Ni(1)[Mo6P4]2填充在其空穴中.更多还原

【Abstract】 Two novel Molybdenum(V) phosphate based inorganic-organic hybrid compounds,(C4H14N3)(C4H15N3)4{Na[Mo6O15(H2PO4)4]2}·8H2O(compound 1) and {Ni[Mo6O15(H2PO4)4]2}(4,4′-bipy)3·H2O(compound 2) were hydrothermally synthesized and characterized by elemental analysis,IR,and single crystal X-ray diffraction.They are both supermolecular structures costructed by hydrogen-bonding between the sandwich-like Na/Ni(Mo6P4)2 units and organic molecules.In compound(1),two rings of six and one octahedra, tetrahedron construct a centrosymmetric structure.In compound(2),Ni(2)[Mo6 P4]2 and protonated 4,4′-bipy construct a layer structure along bc plane,with cavity occupied by alkylated 4,4′-bipy and water molecules.更多还原
