Lead(II)-Azido Metal–Organic Coordination Polymers: Synthesis, Structure and Application in PbO Nanomaterials Preparation

Abstract

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.

Synthesis and Structures of Lead(II) Complexes with Substituted Derivatives of the Closo-Decaborate Anion with a Pendant N3 Group

“…The IR and 11 B NMR data correlate with those reported [53]. by different methods [52], it seems that the softer boron cluster is preferable to form the coordination environment of the metal atom as compared to the azido group. We concluded that the N3 group is too hard to be coordinated by lead(II) in the presence of BH groups.…”

“…The units are interconnected through CH…HB contacts (Figure 6), forming channels parallel to axis c, which are filled with disordered solvent molecules. In spite of the ability of lead(II) to form compounds with the N 3 group coordinated by different methods [52], it seems that the softer boron cluster is preferable to form the coordination environment of the metal atom as compared to the azido group. We concluded that the N 3 group is too hard to be coordinated by lead(II) in the presence of BH groups.…”

“…It is known that the azide ion is able to be coordinated by lead(II) in various ways; in particular, it can act as a tridentate (µ 1,1,1 -N 3 or µ 1,1,3 -N 3 ) and a bidentate bridging ligand (µ 1,1 -N 3 or µ 1,3 -N 3 ) [52]. The obtained derivatives can be used in the synthesis of organometallic coordination polymers; therefore, studies in this field of lead(II) coordination chemistry are topical.…”

N-Ligands mediated Co(Ⅱ) coordination polymer incorporating 5-hydroxyisophthalic acid: Syntheses, structures, and theoretical calculations

“…Metal coordination polymers (CPs) are a promising class of crystalline porous materials composed of metal-containing nodes and organic ligands. Due to their intriguing topology, easyto-functionalize surface structure, and properties in gas storage and separation, ion exchange, sensing luminescence, etc., CPs have drawn a lot of attention in recent decades [1][2][3][4][5][6][7][8][9][10][11][12]. The structure diversity of CPs and their chemical properties are almost limitless on the basis of the properties of metal ions and their coordination modes with various organic ligands.…”

Thickness and Humidity on Proton Conductivity in MOF-508 Thin Film by Twin-Zinc-Source Method

“…There have been several achievements in MOF materials with high proton conductivity by systematic design modifications, such as the introduction of NH 4 + , H 3 O + , and HSO 4 − into the pores of the framework [8]. However, there have been few studies on the physical properties of MOF thin films [9][10][11], such as adjusting the film morphology and the fabrication of dense MOF films [12][13][14]. Therefore, the simple preparation of stable and high proton conductive MOF thin films remains a great challenge [15].…”
