Synthesis, characterization and biological activity of some nickel(II) mixed ligands complexes of dithiocarbamate and 1,10-phenanthroline

Dithiocarbamates: Challenges, Control, and Approaches to Excellent Yield, Characterization, and Their Biological Applications

“…Abbas stated that “these bands are Band I which corresponds to π - π ∗ transitions of the N-C=S group. Band II is assigned to π - π ∗ of S-C=S group and Band III to n - π ∗ transitions” [79]. In coordination compounds, the two transitions are from ligands and excitation of metal ions [71, 79].…”

Transitions from ligands are π - π ∗ and n - π ∗ while transition as a result of excitation of metal ions is called the d-d transition [71, 79].…”

Transitions from ligands are π - π ∗ and n - π ∗ while transition as a result of excitation of metal ions is called the d-d transition [71, 79]. Metal-to-ligand charge transfer (MLCT) and ligand-to-metal charge transfer (LMCT) are due to excitation of an electron from the metal ion to the dithiocarbamate ligands and vice versa [79].…”

This characterization technique is used to support results from other characterization techniques.…”

Antimicrobial, computational, and molecular docking studies of Zn (II) and Pd (II) complexes derived from piperidine dithiocarbamate

“…[1][2][3][4][5][6][7][8][9][10][11] Dithiocarbamate can bond to metal ions in different coordination modes (Chart 2) as (i) monodentate ligands through the sulfur of the CSS − group (A); [10][11][12][13][14][15] (ii) bidentate chelating fashion through the sulfur atoms, through production of two almost equal M-S bonds. In doing so, it forms a small bite angle (S-M-S), ranging from 65 to 80 being dependent upon the size of the ligand and metal ion (B); [7,9, (iii) bidentate bridging mode through the two sulfur atoms or through the one of the sulfur atom only (C); [26,37,[39][40][41] (iv) poly-dentate mode between three center or more (D). [28,37,[42][43][44] Metal complexes of dithiocarbamate present a wide range of applications in agricultural science, medicine as antibacterial, anti-fungal, and anti-inflammatory, industry, analytical, and organic chemistry.…”
