Syntheses and Properties of Hetero-Trinuclear Mn(II)-Cu(II)-Mn(II), Ni(II)-Cu(II)-Ni(II) and Trinuclear Ni(II) Complexes Bridged with N,N′-bis(2-pyridylethyl)dithiooxamidate
Bibliographic record
Abstract
Five Trinuclear metal complexes bridged with N,N′-Bis(2-pyridylethyl)-Dithiooxamidate, [Ni3(Ped)2](ClO4)2(H2O) (1), [Ni3(Ped)2](NO3)2(H2O) (2), [Ni3(Ped)2](Ac)2(H2O)2 (3), [CuNi2(Ped)2](NO3)2(H2O)2 (4) and [CuMn2(Ped)2](NO3)2(H2O)2 (5) (H2Ped = N,N′-Bis(2-pyridylethyl)-Dithiooxamide), have been synthesized and characterized by elemental analyses, IR, UV-Visible spectra, conductance and EPR spectra. Thermal stabilities of the complexes were studied by TG-DTA analysis from room temperature to 600 ℃. The variable temperature magnetic susceptibility for complex 5 has been measured in the temperature range of 1.5~298 K. The effective molar magnetic moment of the complex 5 decreased with temperature at first, and reached the smallest value, 7.0 B.M, at 48 K. When temperature decreased from 48 K, the effective molar magnetic moment increased rapidly. This result indicated the presence of a basic state with high spin in the complex 5.

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; both teacher heads agree on what is shown here.
