RuNH363

RuNH363 is a hypothetical transition-metal cluster discussed in speculative inorganic chemistry and materials science. It is used in theoretical models to explore the properties of ruthenium-nitride–hydride species and to illustrate design principles for small metal clusters that combine nitrido, hydride, and metal centers.

Nomenclature and composition: The designation RuNH363 draws on the chemical symbol Ru for ruthenium, together with NH to indicate nitride–hydride ligation, and the numeral 363 as a model-specific index. In published discussions, exact stoichiometry varies; some proposals describe Ru surrounded by a network of nitrogen-centered ligands with hydride donors, forming a compact core. Others treat 363 as a catalog code rather than a fixed formula. There is no single agreed structure.

Structure and properties: In computational studies, RuNH363 is typically modeled with a ruthenium center bound to several nitrido and hydride ligands, potentially adopting octahedral or distorted geometries. Theoretical assessment focuses on electronic structure, redox behavior, and potential catalytic activity, such as ammonia synthesis or hydrogen storage. There is no experimental synthesis or unambiguous spectroscopic characterization reported in the literature.

Status and context: RuNH363 serves as a conceptual tool to discuss cluster stability, ligand coupling, and the challenges of stabilizing heterometal nitridyl-hydride frameworks. It is not recognized as a verified chemical species or a practical material at this time; any practical relevance remains contingent on future synthesis and validation. Related topics include transition-metal nitride hydride clusters and ruthenium-based catalysts.
