SbRbSr

SbRbSr is a proposed ternary compound consisting of antimony (Sb), rubidium (Rb), and strontium (Sr) in a 1:1:1 ratio. There is no widely cited, peer-reviewed documentation of a stable phase with the exact formula SbRbSr in major chemical databases or standard references, so it is best treated as a hypothetical or exploratory composition within the class of ternary antimonides or pnictide intermetallics that combine alkali and alkaline-earth metals with a pnictogen.

Composition and valence

In a simplified ionic view, Sb would be Sb3− while Rb and Sr would be Rb+ and Sr2+, respectively. This balance can yield a neutral formula unit for SbRbSr. The precise crystal structure and oxidation state distribution would require experimental determination, as multiple structural motifs are possible for ternary alkali/alkaline-earth antimonides.

Synthesis and structure

Synthesis would likely involve high-temperature solid-state reactions of rubidium metal, strontium metal, and antimony under inert or vacuum conditions, potentially in sealed ampoules to minimize oxidation. Flux or orthogonal synthesis routes using Sb-rich melts could be explored. The highly reactive nature of rubidium mandates careful air-free handling. The actual crystal structure, such as a specific intermetallic lattice or a Zintl-type framework, remains speculative until reported data.

Properties and applications

If synthesized, SbRbSr would probably be a solid with substantial lattice energy; its electronic properties (band gap, conductivity) would depend on the structural arrangement. There are no known natural minerals or established applications for this exact composition; any interest would be primarily in fundamental solid-state chemistry and materials science research.

Safety

Handling would require strict inert-atmosphere techniques for the alkali metal components, along with standard precautions for arsenic-free pnictides and antimonides.
