New 2,6-bis-[uracil-imino] ethylpyridine complexes containing the CdN6 core: Synthesis, crystal structures, luminescent properties and antiproliferative activity against C6 glioma cells

“…2.34 Å) because of the different basicity degree. The geometrical features of the uracil rings are very similar to those found in other related uracil derivatives [24,25]. The C2@O carbonyl length (ca.…”

Bonding and structure trends of thiosemicarbazone derivatives of metals—An overview

“…Tetranuclear complexes [Pd 4 L 4 ] 217 and 218 involve binding via C, N 3 , and S-donor atoms [103,244] and complex 219 binds via N 4 , N 3 , S-donor atoms [245]. The coordinate sulfur bridges Pd centres, and the central core Pd 4 S 4 is an eight-membered twisted ring of alternate Pd and S atoms.…”

“…Neutral thiosemicarbazone ligands coordinate via a S-donor atom in complexes 231-247. Complexes have either trigonal planar (231,232) or distorted tetrahedral geometry (233)(234)(235)(236)(237)(238)(239)(240)(241)(242)(243)(244)(245)(246)(247)(248)(249). The geometry of N 3 , S-chelated complex 248 is more distorted.…”

Tetranuclear Complexes of PdII with Tridentate [C,N,O] and [O,N,O] Ligands: Synthesis, Reactivity and Structural Isomerism

“…Even when there is no metal-carbon bond formation, the tetranuclear structure is reached only after deprotonation, as has been reported for a coordination compound derived from a [N,N,S] ligand. [41] The purpose of this paper is twofold: first, to study the activation of aromatic carbon atoms against aliphatic carbon atoms by checking the bonding possibilities of N-phenol Schiff base ligands, and secondly, to determine the…”
