三聚氰胺和对苯二氧乙酸共晶中的三维氢键网络(英文)

3D Supramolecular Hydrogen Bonds Network in Cocrystal of Melamine and p-Phenylenedioxydiacetic Acid

合成了一个新的超分子聚合物{(MAH+)2(p-BDOA2-)·4H2O}n(MA=三聚氰胺;p-BDOAH2=对苯二氧乙酸),通过X-射线对其结构进行了表征。在该聚合物中,三聚氰胺被质子化,相邻的三聚氰胺分子通过氢键形成一维阳离子链(MAH+)n,相邻的阳离子链由p-BDOA2-阴离子连接构成波浪状的二维层,层状结构通过水分子的氢键和π-π堆积形成三维结构。

A new melamine( MA)-p-phenylenedioxydiacetic acid( p-BDOAH2) complex {( MAH+)2( pBDOA2-)·4H2O}n,( 1) had been prepared,and its structure was characterized by X-ray crystallography. In complex 1,the MA molecules are protonated and form cationic( MAH+)nchains via N—H···N hydrogen bonds between adjacent MAH+cations. The chains are connected to each other through p-BDOA2-anions as well as lattice water molecules via extensive hydrogen bonds to form a 3D structure.
