Structural insights into coordination polymers based on 6s2 Pb(II) and Bi(III) centres connected via heteroaromatic carboxylate linkers and their potential applications

Dual-Color 2D Lead–Organic Framework with Two-Fold Interlocking Structures for the Detection of Nitrofuran Antibiotics and 2,6-Dichloro-4-nitroaniline

“…The rational design of MOFs is very challenging and relies on the rational selection of linkers and metal ions. , Carboxylate donor ligands are very important because they have strong coordination abilities in different ways that allow them to meet the geometric needs of metal centers, which leads to higher dimensions and interesting topologies. − Pb­(II), as a heavy metal ion in the p-block, has the characteristics of a large radius and multiple coordination numbers, which provides a unique opportunity for constructing a new type of MOF with variable topology and interesting properties. − However, to date, most of the studies on MOFs have mainly focused on lanthanide elements and d-block transition metals, while less attention has been given to MOFs based on p-block main group metals. , Therefore, the development of innovative Pb-based MOFs and their potential applications is very important.…”

Dinuclear complexes, a one dimensional chain and a two dimensional layer of bismuth(iii) chalcogenones for C–S cross coupling reactions

“…Coordination polymers (CPs) derived from metal salts and organic ligands have significantly contributed to the construction of porous coordination polymers or metal–organic frameworks. 1 A large number of CPs have been reported with transition metals and lanthanide ions, 2 while limited CPs have been accounted with the main group metals such as In, Sn, Bi, etc.…”

“…Herein, we report bismuth coordination polymers derived from imidazole chalcogenone ligands and their catalytic activities. 1,12,13 A unique approach for the functionally important motifs to control the structural versatility in bismuth( iii ) chalcogenones has been investigated along with their efficient role in C–S cross-coupling reactions. Four new bismuth( iii ) chalcogenone complexes, [( L 1 ) 2 BiCl 2 (μ 2 -Cl)] 2 ( 1 ), [{( L 2 )BiCl 2 (μ 2 -Cl)} 2 ] ∞ ( 2 ), [( L 1 )Bi(Br)(μ 2 -Br) 2 ·CH 3 CN] ∞ ( 3 ), and [( L 2 ) 2 BiBr 2 (μ 2 -Br)] 2 ( 4 ), have been isolated from the reaction between BiX 3 (X = Cl, Br) and 1-(2-hydroxyethyl)-3-isopropyl-1 H -benzo[ d ]imidazole-2(3 H )-selone ( L 1 ) or 1-(2-hydroxyethyl)-3-isopropyl-1 H -benzo[ d ]imidazole-2(3 H )-thione ( L 2 ).…”

Structure-Directing Interplay between Tetrel and Halogen Bonding in Co-Crystal of Lead(II) Diethyldithiocarbamate with Tetraiodoethylene

“…Several reviews [ 35 , 36 ] considered the known examples of TeBs that occurred between a tetrel atom (functioning as a σ-hole donor) and a lone-pair possessing atom (acting as a nucleophilic component of the TeB linkage). Most of the recent reports on TeB have been focused on contacts involving carbon atom(s) [ 35 , 37 , 38 , 39 ] or silicon atom(s) [ 40 , 41 ], while TeB including σ-hole-donating tin [ 42 ] or lead sites [ 36 , 43 , 44 , 45 , 46 , 47 ] are still poorly investigated. Notably, before our decade, the ability of lead(II) to act as a Lewis acid in intermolecular contacts was considered in the frameworks of additional coordination contacts, secondary bonding, or semi-coordination [ 36 , 48 ].…”
