La2S14

La2S14 is a chemical formula that would designate a compound composed of two lanthanum atoms and fourteen sulfur atoms. In standard inorganic chemistry, there is no widely accepted, well-characterized compound with this exact stoichiometry. The term may reflect a misnotation, a data-entry error, or the appearance of a fragment within a larger polysulfide or complex in a database rather than a discrete, isolated solid.

Chemical considerations for La2S14 suggest that the formal oxidation state assignment would be problematic. Lanthanum typically adopts a +3 state, while sulfur commonly exists as S2− in simple sulfides. A neutral compound with two La and fourteen S would be far from charge-balanced, implying that if a species with this composition exists, it would likely be a charged polysulfide anion or a component of a salt with countercations, or a fragment of a larger cluster rather than a conventional binary sulfide.

Synthesis and structural data for La2S14 are not reported in peer-reviewed literature or standard chemical databases, and no crystallographic characterization is available. Consequently, there is no established crystal structure, phase information, or reliable physical-property data for this formula. It remains unclear whether the notation represents a genuine compound or a mislabeling of a more common lanthanum sulfide such as La2S3, LaS, or LaS2.
