# Is selenium disulfide polar or non-polar?

So I saw in some internet site that $$\ce{SeS2}$$ is a polar molecule. When I drew the Lewis structure of the molecule, it showed up as a linear molecule like this:

$$\ce{S=Se=S}$$

The electronegativity difference of $$\ce{Se-S}$$ is just $$0.01$$ and the linear form shows that vectors cancel each other. Yet, some websites state that this molecule is polar, when everything to me indicates is a non-polar molecule.

Are they wrong or am I missing something here?

• Selenium disulfide has a composition that approximates to SeS2 and is sometimes called selenium sulfide. However, as used in proprietary formulations, it is not a pure chemical compound but a mixture where the overall Se:S ratio is 1:2. The compounds are Se–S rings containing a variable number of S and Se atoms, SenS8−n. en.wikipedia.org/wiki/Selenium_disulfide – Poutnik Dec 6 '20 at 8:04
