4 Zinc and Cadmium

Design of a Semirigid Molecule as a Selective Fluorescent Chemosensor for Recognition of Cd(II)

“…These sources lead to cadmium exposure through various means, and there is evidence of increasing cadmium accumulation in food and organisms, which will pose severe harm for human health . On the other hand, Cd 2+ and some metal ions, especially Zn 2+ , have many similar properties, thus it is difficult to discriminate between them. ,, Therefore, there is a great need for the design and synthesis of such chemosensors, which have high sensitivity and selectivity for detecting and monitoring Cd 2+ by employing a simple response at physiological pH.…”

Tris(μ-phenoxo) bridged Cd(II) polymer synthesised from a symmetrical tripodal ligand: A novel observation for heptadentate monocapped trigonal antiprismatic Schiff base complex

“…Cadmium is an environmental pollutant which inhibits RNA polymerase activity in vivo [19,20] and reacts readily with proteins and other biological molecules. So the macrocyclic chemistry of cadmium has been developed recently [21]. Although many studies have been made on Cd(II) macrocyclic Schiff base complexes [5, [22][23][24], only a few crystal structures have been reported, and most of them are found to be mononuclear complexes [25][26][27][28][29].…”

“…This indicates that these imino groups have strong coordination ability towards Cd(II). So it is clear from the structural analysis that three imine nitrogens [N (21), N (22), N (27)], one bridgehead nitrogen N (24), and three phenoxy oxygen atoms [O (19), O(35) and O(46)] are arranged at apices of a distorted monocapped trigonal antiprism.…”

Synthesis and characterization of Cd(II) macrocyclic schiff base complex with two 2-Aminoethyl pendant arms

“…The macrocyclic chemistry of cadmium has been developed recently [10][11][12][13]. Previous works mainly focused on dinuclear or oxa-aza *Corresponding author.…”
