Answer: Geometric Isomers of [Co(dien)Br2Cl]

 
There are 4 geometric isomers with this formula. The dien ligand can coordinate either fac or mer, and there can be either a bromide or a chloride trans to the central nitrogen in the dien ligand.
 
 
dien is fac, chloride trans to central N 
dien is fac, bromide trans to central N
dien is mer, chloride trans to central N 
dien is mer, bromide trans to central N
