“…Lead is a main group of toxic heavy metal, and the most important reports are focused on the lead(II) model complexes and the chelating agent of removing lead(II) ion in the biological system. As lead(II) ion has a larger radius, variable stereochemical activity and flexible coordination environment, so this metal ion provides a unique opportunity for new metal coordination compounds [12][13][14][15][16][17][18][19][20].…”

The new neutral binuclear lead(II) azido coordination compound, [Pb ₂(tmph) ₂(μ-N₃)₂(CH₃COO) ₂] (1) [tmph = 3,4,7,8-tetramethyl-1,10-phenanthroline], has been synthesized by a sonochemical method. Single crystal X-ray structure shows that the overall structure of 1 is binuclear unit. Complex 1 has a bridging azido pathway, end-to-end bridging azides between a pair of lead(II) centers. This is further extended into a one-dimensional (1D) and three-dimensional (3D) supramolecular structure by Pb⋯C and π–π weak directional intermolecular interactions. The coordination number of lead(II) ions is seven, PbN₄O₃, with two N-donor atoms from tmph ligands and three O-donors from acetate anions and two N-donors from two azide anions. It has a "stereo-chemically active" electron lone pair, and the coordination sphere is hemidirected. The PbO nanoparticles were obtained by thermolysis of 1 at 180 °C with oleic acid as a surfactant. The morphology and size of the prepared PbO samples were further observed using scanning electron microscopy (SEM).
