Nitrogen fluoride is a bit ambiguous, as there are multiple possible compounds with nitrogen and fluorine.

Here are the most common ones:

* Nitrogen trifluoride (NF₃): This is the most common and stable compound. It has a trigonal pyramidal shape.

* Nitrogen tetrafluoride (NF₄⁺): This is a cation and is extremely reactive. It has a tetrahedral shape.

* Difluoronitrogen (N₂F₂): This compound exists in two isomeric forms: trans-N₂F₂ and cis-N₂F₂.

To be more specific, you need to specify the number of nitrogen and fluorine atoms in the molecule.
