Synthesis and Structures of Dimeric Zinc Complexes Supported by Unsymmetrical Rigid Bidentate Imino- acenapthenone Ligand
Bibliographic record
Abstract
We report two zinc complexes of molecular formulae [ZnCl 2 (Mes - BIAO)] 2 ( 3 ) and [ZnCl 2 (Dipp - BIAO)] 2 ( 4 ) ( Mes = Mesityl, Dipp = 2,6 - diisopropylphenyl) of rigid unsymmetrical bidentate iminoacenapthenone ligands (Mes - BIAO) ( 1 ) and Dipp - BIAO) ( 2 ). The zinc complexes 3 and 4 can be achieved by the reaction of ZnCl 2 and neutral [ N - (mesityl) - iminoacenapthenone] ( 1 ) and [ N - (2,6 - diisopropylphenyl) - iminoacenapthenone] ligand ( 2 ) respectively in dichloromethane at ambient temperature. The solid state structures of the complexes 3 and 4 were established by single crystal X – ray diffraction analysis. In the solid state structures, bo th the complexes are dimeric in nature. In complexes 3 and 4 , each of the zinc coordination polyhedron is formed by the ligation of imine nitrogen, carbonyl oxygen atoms of the ligand 1 and 2 respectively along with three chlorine atoms. Out these three ch lorine atoms, two are 2 bridged with adjacent zinc atom to form the dimer. Thus overall zinc atom is penta - coordinated and the geometry can be best described as a distorted trigonal bipyramidal or a distorted square pyramidal.

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.
