摘要
The title complex,[Pb4（1,2-bdc）4（L）2]·2.25H2O 1（L = 2-（2-chloro-6-fluorophen-yl）-1H-imidazo[4,5-f][1,10]phenanthroline,1,2-H2bdc = 1,2-benzenedicarboxylic acid）,has been obtained by using hydrothermal synthesis and characterized by elemental analysis,IR and single-crystal X-ray diffraction.It crystallizes in monoclinic,space group P21/c with a = 12.0920（6）,b = 18.9248（10）,c = 15.2729（8） ,β = 98.7530（10）°,V = 3454.3（3） 3,Z = 1,C140H90Cl4F4N16O41Pb8,Mr = 4527.60,Dc = 2.176 g/cm3,F（000） = 2130,μ（MoKa） = 9.884 mm-1,R = 0.0241 and wR = 0.0582.Compound 1 exhibits a unique tetra-nuclear structure,and is further stacked by π-π interactions to give a two-dimensional supramolecular layer.The N-H···O and O-H···O hydrogen bonds stabilize the structure of 1.
