报道一个新金属膦酸盐化合物:[Ni(2,2’-bipy)(O2CCH2CH2PO3H)(H2O)](2,2’-bipy=C10H8N2)。通过X射线单晶衍射仪测定其晶体结构,并对其进行元素、红外等性质测定。晶体结构研究结果表明,这个化合物为正交晶系。在这个镍化合物中,两个六配位的Ni(II)离子通过O2CCH2CH2PO3H离子的桥连作用形成一个中心对称的二聚体。这些二聚体进一步通过O-H…O氢键以及π-π堆积作用形成三维超分子结构。
A new metal phosphonate compound is reported: [Ni (2,2’-bipy) (O2CCH2CH2PO3H) (H2O)] (2,2’-bipy = C10H8N2). The crystal structure was determined by X-ray single crystal diffractometer and the elemental, infrared and other properties were measured. The crystal structure of the results show that this compound is orthogonal crystal system. In this nickel compound, two hexacoordinated Ni (II) ions form a centrosymmetric dimer through the bridging of the O2CCH2CH2PO3H ions. These dimers further form three-dimensional supramolecular structures through O-H ... O hydrogen bonding and π-π stacking.
