stannic

I'm a little stuck... Click here to teach me more about this clue!

'tinny' is the definition.
(I've seen this in another clue)

I don't understand how the rest of the clue works.

(Other definitions for stannic that I've seen before include "Of tetravalent tin" , "Relating to a form of tin" , "containing tin" , "Relating to one type of tin" , "Of one form of tin" .)

I've seen this clue in The Guardian.
