Naming structures

As if this could not get any harder, I am now as confused as I ever was on the inorganic part of the class...... and you seem to be the only one that exlpain things in a way that I understand. 1. name this compound by following the IUPAC system. It seems to me like the longest chain is 11 (which I don't know what to call) an ...continues
