Synthesis and Study of a New Kind of Lead Complex with Variable Coordination Numbers

摘要

The crystal C_(18)H_(12)O_(10)Pb3 is synthesized by Pb and phenyl propylene acid. The crystal is characterized by IR and single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group P2_1/c with the crystal cell parameters of a = 15.3263(14) A, b = 16.3479(14) A, c = 8.1006(7) A, β = 92.3060(10)°, V= 2028.0(3) A~3, and Z= 4. Through the molecular structure of complex, we can see that Pb has three kinds of coordination modes (5,6,7). The compound has formed a 1D surface shape structure through these coordinate modes with the ligand, and this 2D layer piles through C—H···π forms the 3D compound.
