Hey all, first post!

Need some help, my Professor gave us a work sheet to figure out the point group symmetry of all of these molecules. Problem is some of them I can find a picture of anywhere on the internet. Any help with these? Any hint about the point group would be helpful too

[Co(mnt)3] 3-    mnt=maleonitriledithiolate anion

Sn(acac)2Cl2  cis and trans  (acac= anion of 2,4-pentaedione)

(CH3ZnOCH3)4

thanks!!

http://en.wikipedia.org/wiki/File:Na2mnt%27.png shows for instance sodium maleonitriledithiolate. Does this look isolobal to anything else you may have covered?

If something has four substituents and has cis and trans isomers, what does that suggest about the structure?

Perhaps see e.g. http://dx.doi.org/10.1107/S056774088000790X ?
