Abstract
Isopropoxy- and tert-butoxy-tris(dithiocarbamato)titanium(IV) complexes of five dithiocarbamate ligands were prepared and characterized by LDI-MS, (1)H NMR, (13)C NMR, and elemental analysis, as well as by crystallographic determination of two examples. Both showed strongly pi-coordinated alkoxy groups and two separate dithiocarbamate coordination environments that, in solution, were in rapid exchange. Cyclic voltammetry in CH(2)Cl(2) revealed irreversible but reproducible oxidation peaks between +1.2 and +1.6 V vs Ag/AgCl, about 1 V positive of those from the free ligands, as well as reduction peaks in the -1.9 to -2.2 V range vs Ag/AgCl assigned to Ti(IV/III) couples, and second reductions in some cases. The corresponding diisopropoxy-bis(dithiocarbamato) analogues were not isolable and slowly transformed to the more stable tris species. Indeed, these were shown to be in slow equilibrium.

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 it
