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 P1, a=9.7399(6), b=11.6535(8), c=12.6806(8), α=62.8050(10), β=78.4910(10), γ=80.5490(10)°, C54H36N8O12Pb4, Mr=1817.67, Z=1, V=1250.04(14)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.
