Tetraxenonogold(II)

Tetraxenonogold(II) is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tetraxenonogold(II) rather than just read about it. In short: Tetraxenonogold(II), gold(II) tetraxenide, or AuXe2+4 is a cationic complex consisting of a central gold atom surrounded by four xenon atoms. It is a covalent complex with a square planar geometry.

Key takeaways

Tetraxenonogold(II) belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tetraxenonogold(II) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tetraxenonogold(II) from memory before moving on to harder problems.

Reference excerpt

Tetraxenonogold(II), gold(II) tetraxenide, or AuXe2+4 is a cationic complex consisting of a central gold atom surrounded by four xenon atoms. It is a covalent complex with a square planar geometry. The complex is found in the compound AuXe2+4(Sb2F−11)2 (tetraxenonogold(II) undecafluorodiantimonate). This compound, which exists in triclinic and tetragonal crystal modifications, has the AuXe2+4 ion that is stabilised by interactions with the fluoride atoms of the counterion. The Au−Xe bond length is 274 pm (2.74 Å). Tetraxenonogold(II) is unusual in that it is a coordination complex of xenon, which is weakly basic. It is also unusual in that it contains gold in the +2 oxidation state. It can be produced by reduction of gold(III) fluoride (AuF3) by xenon in the presence of fluoroantimonic acid. The salt crystallises at low temperature. It was the first description of a compound between a noble gas and a noble metal. It was first described in 2000 by Konrad Seppelt and Stefan Seidel. Several related compounds containing gold(III)–xenon and gold(I)–xenon bonds have since been isolated.

Worked examples

Example 1 — a first encounter with Tetraxenonogold(II)

Start with the simplest possible case. Write down what Tetraxenonogold(II) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tetraxenonogold(II) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tetraxenonogold(II) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tetraxenonogold(II)

In research: Tetraxenonogold(II) appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tetraxenonogold(II) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tetraxenonogold(II) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cations, Gold compounds, Inorganic compound stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Tetraxenonogold(II) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
