Synthesis and Physicochemical Studies of Some 2-substituted-1-phenyl-1,3-butanedionato Nickel(II) and Copper(II) Complexes And Their 2,2?-Bipyridine and 1,10-Phenanthroline Adducts
Bibliographic record
Abstract
The nickel(II) and copper(II) complexes of 2-substituted-1-phenyl-1,3-butanedione (2-R-bzacH, R=Cl, NO2) andtheir 2,2′-bipyridine (bipy) and 1,10-phenanthroline (phen) adducts have been synthesized and characterized bymicroanalysis, conductance, magnetic and spectral measurements. The conductivity measurements in nitromethaneindicate that the complexes are non-electrolytes while all the adducts are electrolytes except Ni(NO2-bzac)2bipy andCu(NO2-bzac)2phen which are non-electrolytes. The room temperature magnetic moments suggest that theCu(NO2-bzac)2 is a dimer while the visible absorption spectra of the compounds suggest plausible 4-, 5- and6-coordinate geometry for these compounds. The infrared spectra of the complexes showed that lower frequencyshifts of varying magnitudes were observed in the carbonyl stretching frequencies on complexation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
