摘要

A new 3D supramolecular complex,namely dimethylammonium 4,4'-([2,2'-bipyrimidine]-5,5'-diyl)bis(2-hydroxybenzoate)dihydrate,has been synthesized by the reaction of 4,4'-([2,2'-bipyrimidine]-5,5'-diyl)bis(2-hydroxybenzoic acid)with aqueous dimethylamine solution and characterized by single-crystal X-ray diffraction,1H NMR spectroscopy and elemental analysis.It belongs to triclinic system,space group P-1 with a = 6.5539(4),b = 9.4977(6),c = 12.1407(8)?,a = 72.299(6),β = 89.160(5),γ= 70.797(8)°,V = 676.52(8)?3,Z = 1,Mr = 556.57,μ = 0.103 mm-1,Dc = 1.366 g/cm3,F(000)= 294,the final R=0.0828 and wR = 0.2083 for 1934 observed reflections with Ⅰ＞2a(Ⅰ).The 4,4'-([2,2'-bipyrimidine]-5,5'-diyl)bis(2-hydroxybenzoic acid)dianion,dimethylammonium cation,and water molecule are interconnected by O-H…O,N-H…N,and N-H…O hydrogen bonds,forming a two-dimensional(2D)layer.Two adjacent 2D layers are further stacked into a three-dimensional supramolecular structure through O-H…O hydrogen bonds.In addition,the luminescent property of this supramolecular complex has also been investigated.
