Tetrel bonding stabilization of a new coordination polymer constructed from lead(ii) azide and 1-(pyridin-2-yl)ethylidenepicolinohydrazide

Abstract

In this work we report on a new PbII coordination polymer [Pb3L2(N3)4]n, which was obtained from Pb(N3)2 and 1-(pyridin-2-yl)ethylidenepicolinohydrazide (HL). Complex exhibits a 1D polymeric chain, constructed from the {[Pb3(N3)4]2+}n...

On the pivotal role of tetrel bonding in the supramolecular architectures of PbII–NCS complexes with chelating thiosemicarbazide derivatives

“…The utilization of lead in crystal engineering, particularly through the formation of Pb⋯O, S, N tetrel bonds, represents an interesting aspect of material science and inorganic chemistry. 24–41 Tetrel bonding, involving the interaction between a group 14 element 42,43 (like lead) and an electron rich atom (such as oxygen, sulfur or nitrogen), is pivotal in the construction of intricate crystal structures. 44 In this context, lead, with its large atomic radius and significant polarizability, forms strong and directionally specific interactions with a variety of electron donors, including π-systems.…”

“…45 These tetrel bonding interactions are instrumental in dictating the assembly and properties of crystal networks. 24–45 This approach in crystal engineering not only broadens the horizon for creating new materials but also offers deep insights into the fundamental interactions governing the assembly of complex crystal structures.…”

A lead(ii)–N′-isonicotinoylpyrazine-2-carbohydrazonamide complex system as a converter of aerial carbon dioxide to carbonate under electrochemical conditions with the formation of a single-component white light-emitting phosphor

“…With all this in mind and in continuation of our comprehensive studies in the coordination chemistry of hemidirected Pb 2+ architectures as well as in shedding light on the role of noncovalent interactions in the formation of extended structures, 24–41 we have concentrated on N ′-isonicotinoylpyrazine-2-carbohydrazonamide (HL), 42 which was intentionally designed to serve as a potentially bridging ligand, in the reaction with lead as a complexing agent. To shed light into the nature of Pb⋯O tetrel bonds, DFT calculations have been used along with MEP surface and QTAIM analyses.…”
