Reference excerpt

Sodium maleonitriledithiolate is the chemical compound described by the formula Na2S2C2(CN)2. The name refers to the cis compound, structurally related to maleonitrile ((CH(CN))2). Maleonitriledithiolate is often abbreviated mnt. It is a "dithiolene", i.e. a chelating alkene-1,2-dithiolate. It is a prototypical non-innocent ligand in coordination chemistry. Several complexes are known, such as Ni(mnt)2]2−.

The salt is synthesized by treating carbon disulfide with sodium cyanide to give the cyanodithioformate salt, which eliminates elemental sulfur in aqueous solution:

8 NaCN + 8 CS2 → 4 Na2S2C2(CN)2 + S8 The compound was first described in 1958.

Worked examples

Example 1 — a first encounter with Sodium maleonitriledithiolate

Start with the simplest possible case. Write down what Sodium maleonitriledithiolate 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 Sodium maleonitriledithiolate 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 Sodium maleonitriledithiolate 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 Sodium maleonitriledithiolate

In research: Sodium maleonitriledithiolate 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 Sodium maleonitriledithiolate 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: Sodium maleonitriledithiolate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alkene derivatives, Nitriles, Sodium compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Sodium maleonitriledithiolate 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.
