1,3-Bis(2,2′:6′,2′′-terpyridin-4′-yl)benzene, a new dinucleating bis(tridentate) ligand, as its dichloromethane solvate
Bibliographic record
Abstract
The title compound, 1,3-bis(2,2′:6′,2′′-terpyridin-4′-yl)benzene dichloromethane solvate, C36H24N6·CH2Cl2, is a new ligand suitable for bridging two metal centres. Though not in binding conformations, its two terpyridine units are linked in a unique arrangement, through a meta-phenylene core, which disallows resonance communication between binding sites, as reflected by the crystal structure of its 1:1 CH2Cl2 solvate. The two terpyridine units are related by crystallographically imposed twofold symmetry, forming a 30.02 (8)° dihedral angle with the phenylene core, but with fairly coplanar pyridine rings within. The solvent molecule is disordered over the twofold axis.

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; a candidate call from one teacher head, not a consensus.
