Reaction of 8-hydroxyquinoline(HQ)with Pb(NO3)2 in water resulted in the formation of a tetranuclear complex[Pb4(HQ)6(NO3)2]1.It has been characterized by IR,elemental analyses and X-ray diffraction.Crystal data for this complex:triclinic system,space group P-1,a=9.7399(6),b=11.6535(8),C=12.6806(8)(A),α=62.8050(10),β=78.4910(10),γ=80.5490(10)°,C54H36N8O12Pb4,Mr=1817.67,Z=1,V=1250.04(14)(A)3,Dc=2.415 g/cm3,μ=13.503 mm-1,-12≤h≤8,-14≤K≤13,-15≤l≤15,F(000)=840,Rint=0.0217,R=0.0348 and wR=0.0927.X-ray crystal structure analysis revealed that in 1 each Pb(Ⅱ)contains a stereo-chemically active lone pair of electrons.The Pb…C interaction,C-H…O weak interaction and π…π stacking interactions are observed in the complex.In the solid state,the complex possesses strong photoluminescent emission at 485 and 528 nm.
