This is easier if you post an actual picture instead of a picture inside a word document.

Might be helpful if you listed the symmetry elements present in the molecule?

this is the formula, since i can't place the pic directly here

Well, the first step in figuring out the point group symmetry is to determine the principle rotation axis.

Posting a pic is under the 'Additional Options' tab, though you need to be able to extract a picture from Word and save it as a jpg or something in order to get the file itself.  I've done so and posted it here so we can have a discussion.

Yes.  Now look for C2 axes perpendicular to the principle axis.  Are there any?  If so, how many?  Also look for mirror planes perpendicular to, or parallel to the principle axis.
