Synthesis and characterization of mono- and bimetallic complexes of Zn(II) and Cu(II); new multifunctional unsymmetrical acyclic and macrocyclic phenol-based ligand
Bibliographic record
Abstract
The dicompartmental macrocyclic ligand (L 2 ) 2-was prepared by [1:1] cyclic condensation of N,N-dimethyacetate-N,N-ethylene-di(5-methyl-3-formyl-2-hydroxybenzylamine with 1,3diaminopropane. The ligand includes dissimilar N(amine) 2 O 2 and N(imine) 2 O 2 coordination sites sharing two phenolic oxygen atoms and containing two methyl acetate pedant arms on the amine nitrogen donor atoms. A series of mono-and bimetallic complexes were synthesized and characterized on the basis of elemental analysis, molar conductance measurement, IR and UV-Vis spectroscopy techniques. It was found that during the cyclization process the copper (II) displaced from the N(amine) 2 O 2 to the N(imine) 2 O 2 coordination site and one of the methyl acetate pedant arms is dissociated. The heterodinuclear complex of [ZnL 2 Cu(-OAc)] + was prepared by a transmetallation reaction on the [ZnL 2 Zn(-OAc)] + by Cu(II). The characterization results showed that the two metal ions are bridged by two phenolic oxygen atoms and an acetate group, providing distorted five-coordination geometries for the both metal ions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
