Abstract
In this perspective we report on recently accumulated data on the synthesis and coordination chemistry of 2,4,6-tris(2-pyrimidyl)-1,3,5-triazine (TPymT). Although a highly attractive ligand, owing to the presence of three fused terpyridine-like coordination pockets, the coordination chemistry of TPymT has something of a chequered past. This can principally be attributed to the hydrolysis of the ligand, which readily occurs under mild conditions. Thus, after first being synthesised in 1959 it had only been used a handful of times to synthesise coordination compounds until we began reinvestigating its chemistry in early 2013. Despite the significant challenges associated with its use, our work over the past two years has demonstrated that coordination chemistry with TPymT is indeed possible. Herein, we describe an overview of this body of work as it stands, and discuss its potential impact in a variety of areas including porous materials, catalysis and crystal engineering.

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
