Metallotectons: Comparison of Molecular Networks Built from Racemic and Enantiomerically Pure Tris(dipyrrinato)cobalt(III) Complexes
Bibliographic record
Abstract
The structures of a series of crystalline chiral tris(dipyrrinato)cobalt(III) complexes were determined. The peripheries of the selected complexes bear three trigonally directed substituents known to engage in various intermolecular interactions, including COOH, CN, diaminotriazinyl (DAT), and Br. To allow comparison, structures were determined for both racemic and enantiomerically pure complexes in all cases, except that of the Br-substituted compound. The ability of COOH and DAT groups to participate in well-established patterns of intermolecular hydrogen bonding led to structures with predictable features. In particular, crystallization of the racemic DAT-substituted complex yielded a structure built from open hydrogen-bonded sheets, and a significant fraction of the volume of the crystals (40%) proved to be available for the inclusion of guests. Weaker C−H···N and C−H···Br interactions were observed in the structures of the CN- and Br-substituted complexes, which yielded networks that were found to be more closely packed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
