Bond angles of TeCli4

Postby Yinhan_Liu_1D » Sat Oct 29, 2016 5:57 pm

In the solution manual, it mentioned the Cl-Te-Cl bond angle could be approximately 90 degrees and 120 degrees.

Since there is a bent on the original see-saw shape due to the lone pair, does the 120 refer to the original 180 degree between the axial Cl-Te bond?

Does the 90 degree replace the original 120 degree between the equatorial bonds?

I don't understand why it is 90 and 120.

I would really appreciate your help!

Best,

So in TeCl4 the lone pair pushes the bonded pairs away which causes the angles to be slightly less than 90 and 120 degrees. The 90 degrees is the axial bond angle in the vertical plane and the 120 degree is the equatorial bond in the horizontal plane.

Hope that helps!
