Catalytically active coordination polymer with a tiny Zn₂Se₂ring bridged by bis-selone

Abstract

A highly strained Zn2Se2 ring system incorporated in a one-dimensional coordination polymer has been prepared and used as a catalyst in substituted 8-hydroxy-2-quinolinyl synthesis through Knoevenagel condensation reaction.

Proton reduction by a bimetallic zinc selenolate electrocatalyst

“…It is worth noting that, despite several reports on the structurally characterized mercury selenolate complexes, limited examples of structurally characterized zinc selenolates are available. [31][32][33][34][35][36][37][38] Herein, suitably positioned nitrogen and oxygen donor atoms in the ligand presumably stabilized bimetallic zinc core. Characterization of zinc and mercury selenolate complexes 1 and 4 by 77 Se NMR, which is a very sensitive technique towards the electronic environment around the selenium nucleus, revealed signicantly downeld shi (d ¼ À85 and 76 ppm, respectively) as compared to the diselenide 3 (d ¼ 400 ppm).…”

Uncoordinated‐substituents‐induced zinc(II) coordination polymers exhibiting multifunctional fluorescent sensing activity for cations, anions and organochlorine pesticides

“…An in-depth structural analysis revealed a number of detailed differences. a) Although all of the Zn 2 + are in the 4 S1-S3). b) The dicarboxylates in CPs 1-3 are all in μ 1 -η 1 : η 0 /μ 1 -η 1 : η 0 modes.…”

“…Coordination polymers (CPs) are a kind of inorganic-organic hybrid materials which are self-assembled by metal centers and organic ligands through coordination bonds. [1][2][3] Because of its structural diversity and excellent chemical stability, it has potential application prospects in catalysis, [4] gas adsorption and separation, [5][6][7] electrochemistry [8,9] and other fields. The main factors affecting the formation of CPs are metal ions, types of organic ligands, coordination modes of carboxylic acids and so on.…”

Polytorsional-amide/carboxylates-directed Cd(ii) coordination polymers exhibiting multi-functional sensing behaviors

“…29,30 Among many uorescent sensing materials, coordination polymers (CPs) selfassembled by d 10 metal centers and organic ligands are considered as a kind of excellent sensor used for qualitative and quantitative detection of heavy metal ions, organic pesticides, antibiotic. [31][32][33][34][35][36][37] However, some of these sensors have relatively single detection objects. [38][39][40] Thus, it is of great signicance to develop complex-based sensing materials with multifunctional detection response, which is also a challenge facing this eld at present.…”
