Lewis structure

  1. Sep 16, 2014 #1
    1. The problem statement, all variables and given/known data
    How can I draw a Lewis dot structure for octathiocane (S8) which is non-cyclic, net neutral, and which does not violate the octet rule?

    2. Relevant equations

    3. The attempt at a solution
    First, I tried drawing a straight chain molecule, but the two terminal sulfurs each have a negative charge, giving a net negative charge overall.

    I then tried pushing an electron pair from one of the terminal sulfurs inwards, which solves the charge issue but makes the penultimate sulfur on one side violate the octet rule...

    I'm stumped. Any advice?

    - It is a straight chain.
    - One end has a 1- formal charge, the other has a 0 formal charge. (Net charge=0)
    - Sulfur can change lone pairs to bonds.

    You should be able to figure it out with this, if not let me know. :D
