【Abstract】 A new metal-organic lead( II) complex [Pb( L4)2( NO3)2]( L4 = pyridine-4-carboxaldehyde and 4-aminoantipyrine) has been solvothermally synthesized and structurally characterized by elemental analysis,IR,XRD,and single-crystal X-ray diffraction. The results show that the compound belongs to monoclinic system with space group Cc and cell parameter: a = 2. 3842( 3) nm,b = 0. 97378( 11) nm,c = 1. 9611( 2) nm,α = 90°,β = 128. 836( 9) °,γ = 90°,V = 3. 5466( 7) nm3,Z =4,Dc =1. 715 Mg/ m3,F( 000) =1808,μ = 4. 823 mm- 1,R1= 0. 0476,ωR2= 0. 1158 [I > 2σ( I) ]. The lead( II) complex exhibits strong fluorescence absorption at 470 nm( λmax) in the solid state at room temperature.更多还原
