Unable to generate the structure for cycloprop-1-en-3-ylidene-1-nitrile

[vthimmakondu]

While OPSIN generates the structure if I type the name like cycloprop-1-en-1-nitrile (or simply cyclopropen-1-nitrile) , it complains that nitrile is uninterpretable as soon as a carbene comes into the picture. Any thoughts?

I believe that nitrile takes precedence over carbene in functional group ordering. Please, let me know if I am wrong about this. Of course, if I do use "cyano" as prefix (1-cyanocycloprop-1-en-3-ylidene) then I could generate the structure. But, is that correct way of naming?
