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.
The title complex, [Pb4 (1,2-bdc) 4 (L) 2] 2.25H2O 1 (4-floro- [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, MoKa = 9.884 mm-1, R = 0.0241 and wR = 0.0582. Compound 1 exhibits a unique tetra-nuclear structure, by π-π interactions to give a two-dimensional supramolecular layer. NH ··· O and OH ··· O hydrogen bonds stabilize the structure of 1.
