here's what I did:

$\displaystyle \hat{v}=\frac{v}{\left \| v \right \|}=\frac{(i,i,0)}{\sqrt{i^2+i^2+0}}=\frac{(i,i,0) }{\sqrt{-2}}=\frac{(i,i,0)}{2i}=(\frac{i}{2i},\frac{i}{2i}, 0)=(\frac{1}{2},\frac{1}{2},0)$

but $\displaystyle \hat{v}$ length is not 1, since: $\displaystyle \left \| \hat{v} \right \|=\sqrt{(\frac{1}{2})^2+(\frac{1}{2})^2+0}=\frac{ 1}{\sqrt{2}}\neq 1$

thanks in advanced!
