The current study aims to explain recent developments in the synthesis of Pb(II)-azido metal-organic coordination polymers. Coordination polymers are defined as hybrid materials encompassing metal-ion-based, organic linkers, vertices, and ligands, serving to link the vertices to 1D, 2D, or 3D periodic configurations. The coordination polymers have many applications and potential properties in many research fields, primarily dependent on particular host–guest interactions. Metal coordination polymers (CPs) and complexes have fascinating structural topologies. Therefore, they have found numerous applications in different areas over the past two decades. Azido-bridged complexes are inorganic coordination ligands with higher fascination that have been the subject of intense research because of their coordination adaptability and magnetic diversity. Several sonochemical methods have been developed to synthesize nanostructures. Researchers have recently been interested in using ultrasound in organic chemistry synthetics, since ultrasonic waves in liquids accelerate chemical reactions in heterogeneous and homogeneous systems. The sonochemical synthesis of lead–azide coordination compounds resulted from very fantastic morphologies, and some of these compounds are used as precursors for preparing nano lead oxide. The ultrasonic sonochemistry approach has been extensively applied in different research fields, such as medical imaging, biological cell disruption, thermoplastic welding, food processing, and waste treatment. CPs serve as appropriate precursors for preparing favorable materials at the nanoscale. Using these polymers as precursors is beneficial for preparing inorganic nanomaterials such as metal oxides.

A novel nano, cauliflower-shaped lead(II) metal-organic coordination polymer, [Pb(μ-2-pinh)(N3)OH2]n (1), was synthesized using an ultrasonic method. The nanostructure was characterized by scanning electron microscopy (SEM), X-ray powder diffraction, IR spectroscopy, elemental analysis and thermal analysis. The compound was structurally characterized by single-crystal X-ray diffraction and takes the form of a zigzag onedimensional polymer in the solid-state. The coordination number of the lead(II) ions is six (PbN4O2), with one oxygen and three nitrogen donor atoms derived from two linker organic ligands, one nitrogen atom from a terminal azide anion and one oxygen from coordinated water. It has a stereochemically active lone electron pair, and the coordination sphere is hemidirected. The zigzag 1D chains interact with neighbouring chains through weak interactions, creating a 3D supramolecular metal-organic framework. Lead oxide nanoparticles were obtained by thermolysis of the new nano coordination compound at 180 °C with oleic acid as a surfactant. The morphology and size were further studied using SEM. Natural bond orbital (NBO) analyses demonstrate the electronic properties of the lead centre and other atoms.

The novel nano lead(II) 1D zigzag coordination polymer [Pb(p-2-einh)ClO 4 (MeOH) 2 ] n (1) (p-p-2-einh = (1-(pyridin-2-yl)ethylidene)isonicotinohydrazide) was synthesized by a sonochemical method. The new nanostructure was characterized by using scanning electron microscopy (SEM) and high-resolution transmission electron microscopy, X-ray powder diffraction and elemental analysis. The single-crystal X-ray analysis reveals a one dimensional zigzag coordination polymer structure for 1, that is further extended into a three-dimensional (3-D) supramolecular structure by p-p and other labile intermolecular interactions. The coordination number of the lead(II) ions is six, PbN 3 O 3 . The PbO nanoparticles were obtained by the thermolysis of 1 at 180°C in presence of oleic acid as a surfactant. The Scherrer equation estimated the average diameter of the nanoparticles to be 15 nm. The morphology and size of the prepared PbO samples were further observed using SEM. The structure of the title complex has been optimized by density functional theory calculations. Calculated structural parameters and IR spectra for the title complex are consistent with the crystal structure.
