$\left[\left(CuCl\right)_{2} \left(\right. O = C \left(NH\right)_{2} \left(\left.\right)_{2}\right)\right]$

$\left[\right.Cu\left(\right.O=C\left(\right.NH_{2}\left(\left.\right)_{2}Cl_{2}\left]\right.$

$\left[\right.CuCl_{2}\left(\right.O=C\left(\right.NH_{2}\left(\left.\right)_{2}\left(\left.\right)_{2}\left]\right.$

Solution:

The formula for the complex dichlorobis(urea)copper(II) is $\left[\right.CuCl_{2}\left(\right.O=C\left(\right.NH_{2}\left(\left.\right)_{2}\left(\left.\right)_{2}\left]\right.$ .
