“…On the other hand, the growing interest in s-triazine derivatives specially its chlorinated derivative (cyanuric chloride) and its efficient reaction with hydrazine to render mono-, di-, or tri-substituted hydrazino derivatives has increased [20][21][22]. Several prepared and well explored hydrazino-s-triazine derivatives were reported and considered with special interest in coordination chemistry and supramolecular chemistry [23,24] as well as their enormous potential in the field of material chemistry [25,26], complexation with large metal ions [27][28][29][30][31][32][33][34][35][36], and pharmaceutical industry [37][38][39][40][41][42][43]. 2…”

The present work represents the synthesis, characterization, and antimicrobial studies of novel series of 2,4-bis(hydrazino)-6substituted-1,3,5-triazine and their Schiff base derivatives. IR, NMR ( 1 H and 13 C), elemental analysis, and LC-MS characterized the prepared compounds. The biological activity of the target products was evaluated as well. Twenty-two of the prepared compounds were selected according to their solubility in aqueous DMSO. Only eight compounds showed good activity against the selected pathogenic bacteria and did not show antagonistic effect against fungus Candida albicans. Two compounds k and g have widerange effect presently in Gram-positive and Gram-negative bacteria while other compounds ( f, i, m, d, i, and h) showed specific effect against the Gram-negative or Gram-positive bacteria. The minimum inhibitory concentration (MIC, g/mL) of f, i, k, and h compounds against Streptococcus mutans was 62.5 g/mL, 100 g/mL, 31.25 g/mL, and 31.25 g/mL, respectively. The MIC of m, k, d, g, and h compounds against Staphylococcus aureus was 62.5 g/mL, 31.25 g/mL, 31.25 g/mL, 100 g/mL, and 62.5 g/mL, respectively. The MIC of k, g, and i compounds against Salmonella typhimurium was 31.25 g/mL, 100 g/mL, and 62.5 g/mL, respectively. The MIC of i compound against Escherichia coli was 62.5 g/mL.

“…The bond lengths in all the complexes are unexceptional, albeit at the lower side of the range generally found for complexes of these metal ions with N4O4-donor environment [59][60][61][62][63]. Expectedly, for a given metal ion M-O distances are considerably shorter than the M-N distances.…”

Pincer ligands are interesting chelating agents due to their high ability to motivate the metal ion characteristics leading to diverse types of applications. These ligands and their metal complexes are smart materials which have a great impact in the development of diverse applications helped alot in the advancement of the field of coordination chemistry. In homogenous catalytic transformations, pincer ligands improved the chemical and thermal stability that serve to minimize the leaching of the metal during the catalytic cycle. Also, they offered the ability to fine‐tune the electronic properties for the metal center, thereby increasing the scope of their coordination chemistry and applications especially the pincer ligands comprising s‐triazine core. This review discusses some of the general synthetic protocols of these s‐triazine pincer ligands and their metal complexes with various applications in different fields. In addition, their structural diversity and the ligand coordination behaviors with different metal ions were also explored.
