Answer: Diamminebis(ethane-1,2-diamine)cobalt(III) chloride.

Solution

Alphabetical order of ligands: ammine before ethane-1,2-diamine (en takes the multiplier 'bis' since its name already contains 'di').
All ligands neutral; three Cl⁻ outside ⇒ Co is +3.

Diamminebis(ethane-1,2-diamine)cobalt(III) chloride
