Identify the heteroleptic complex from the following.

The total number of coordination sites in ethylenediaminetetraacetate $(EDTA^{4-})$ is

$A$ coordination compound of cobalt contains five ammonia molecules,one nitro group,and two chlorine atoms per cobalt atom. One mole of this compound produces three moles of ions in an aqueous solution. Reaction of this solution with excess $AgNO_3$ yields two moles of $AgCl$ precipitate. What is the ionic structure of this complex?
