A new cadmium(II) complex with bridging dithiolate ligand: Synthesis, crystal structure and antifungal activity study

Abstract

A new polymeric complex of Cd(II) with 1,1-dicyanoethylene-2,2-dithiolate [ i-MNT 2-= S2C:C(CN)2 2-] as a bridging ligand has been synthesized and characterized on the basis of spectroscopy and single-crystal X-ray diffraction analysis. Single crystal X-ray diffraction analysis reveals that the cadmium (II) complex is six coordinated 1D polymeric in nature. Biological screening effects in vitro of the synthesized polymeric complex has been tested against five fungi Synchitrium endobioticum, Pyricularia oryzae, Helminthosporium oryzae, Candida albicans(ATCC10231), Trichophyton mentagrophytes by the disc diffusion method. In vitro antifungal screening indicates that the complex exhibits fungistatic and fungicidal antifungal activity whereas K2i-MNT.H2O became silent on Synchitrium endobioticum, Pyricularia oryzae, Helminthosporium oryzae, Candida albicans (ATCC10231), Trichophyton mentagrophytes.

Competitive Sorption of Metal Ions on Titanium Phosphate Sorbent (TiP1) in Fixed-Bed Columns: A Closed-Mine Waters Study

“…2+ and faster exchange of coordinated water molecules. 35 It is noticeable that no substantial metal ion sorption leaps are observed in the case of closed-mine water, while the affinity order of metal ions is kept similar to the one established for the model water system. A sorption leap would mean a concentration outbreak inside the column that did not occur in this case.…”

“…The last two metal ions in the order should be considered separately due to physical/chemical reasons. Under the column pH conditions the aluminum ions are known to form the following species Al­(OH) 2 + and Al­(OH) 2+ (pH ≈ 4.5–5.5), hence the observed somewhat higher affinity to aluminum ions. , For the cadmium ions, one possible explanation could be related to the size of the d 10 -cadmium ions being bigger than the zinc ions, which ensures easier formation of Cd­(H 2 O) 6 2+ and faster exchange of coordinated water molecules …”

Metal-Based Drugs in Cancer Therapy

“…At the heart of metallodrugs is coordination chemistry, which explores the interaction between metal ions and ligands. By carefully selecting ligands and metal ions, researchers can fine-tune the chemical properties of metal-based drugs, influencing their stability, reactivity, and biological activity Adhikari et al, 2021;Ghosh et al, 2011;Ghosh et al, 2017;Park et al, 2012;Park et al, 2012;Singh et al, 2017;Singh et al, 2018).…”

Crystal structure, Hirshfeld surface analysis, conduction mechanism and electrical modulus study of the new organic–inorganic compound [C8H10NO]2HgBr4

“…These hybrids hold potential applications in diverse fields such as medicine, biology, catalysis, magnetism, photochemistry, and electrochemistry. 1–3 Furthermore, these compounds have the potential to integrate advantageous characteristics from both organic and inorganic moieties in crystalline molecular-scale composites. 4–7 On the one hand, inorganic materials can have a wide range of electrical properties, mechanical hardness, thermal stability and dielectric and magnetic transitions.…”
