Insights into the Thermal Decomposition Mechanism of Molybdenum(VI) Iminopyridine Adducts
Bibliographic record
Abstract
Understanding the thermal behavior of vapor phase precursors is important to assess their potential for thin film deposition processes and to discern decomposition pathways. Here we present a series of dichloromolybdenum(VI) compounds on three different frameworks: the bis(alkylimido)-, dioxo- and mono(alkylimido)mono(oxo), which is the first foray into understanding the potential differences of decomposition mechanisms for molecules using these strongly bonded ligands. We report the synthesis of three novel metal complexes which have been fully characterized by spectroscopic techniques as well as single-crystal X-ray diffraction (SCXRD) and thermal analysis. Through in situ thermolysis reactions, we show the decomposition of all compounds generates the free N, N ′-chelate ligand. Further thermal decomposition deviated from previously reported γ-H elimination, showing that the presence of β-hydrogens in the complexes provided alternative low-temperature decomposition pathways.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
