# The 465 complex

1. The problem statement, all variables and given/known data
I found out this reaction series in my textbook which is as:
$2Cu(NO_3)_2+2Na_2S_2O_3 \longrightarrow Cu_2(NO_3)_2 +Na_2S_4O_6+2NaNO_3$
$Cu_2(NO_3)_2+Na_2S_2O_3 (excess) \longrightarrow Na_4[Cu_6(S_2O_3)_5]$
Though it is not balanced(latter one) but my question is about the complex that is formed. What is it's geometry and what is the hybridisation of $Cu$ in this complex?

2. Relevant equations

3. The attempt at a solution
I don't know. I have never seen any thing like this before. It's an awkward looking compound but still I have curiosity how these type of monsters are made up.
