Abstract
Metal(II) complexes of 4-amino-6-hydroxy-2-mercaptopyrimidine were synthesized and characterised by electronic and infrared spectroscopies, conductance, melting point and room temperature magnetic susceptibility measurements {M = Mn, Fe, Co, Ni, Cu and Zn}.The molar conductance measurements in DMSO revealed that the Co(II) complex was a 1:1 electrolyte, and the Cu(II) and Zn(II) complexes were 1:2 electrolytes respectively.Infrared spectra indicated that the ligand coordinated through N2 chromophores.Electronic spectra and magnetic moments revealed that all the complexes were octahedral and paramagnetic with the exceptions of the Cu(II) and Zn(II) complexes which were square-planar/ tetrahedral and diamagnetic.In addition, the Mn(II) and Cu(II) complexes exhibited antiferromagnetism.The antibacterial studies revealed that the metal complexes were mostly active against B. cereus and S. aureus, exhibited selective activity towards P. mirabilis and were mostly inactive against E. coli, P. aeruginosa, K. oxytoca and S. aureus.

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.
