Sb5n

Sb5N, occasionally written Sb5n, is a proposed compound in the antimony–nitrogen system. The formula implies a stoichiometry of five antimony atoms for each nitrogen, but the exact nature—whether a discrete molecular cluster, a solid-state phase, or a mixture of species—has not been established in experimental work.

Structures suggested by theoretical studies include motifs where a single nitrogen center is coordinated by several

Synthetic attempts have not produced a confirmed, reproducible preparation of Sb5N. Proposed routes include high-temperature solid-state

Because the structure is not known experimentally, predicted properties are highly model-dependent. If realized, Sb5N would

Status: Sb5N remains speculative. It is cited mainly in theoretical investigations and as part of broader discussions
