(II) Write the formulas for the following coordination compounds. (a) Hexaamminecobalt(III) pentachlorocuprate(II) (b) Ammonium bis(oxalato)dinitrosylchromate(III)

A) Using a cobalt (III) ion as the central metal atom, and with chloride ions (Cl-) and ammonia (NH3) molecules as the ligands, draw both isomers of the coordination complex that will exhibit fac/mer isomerism. B) Using a platinum (II) ion as the central metal atom, with chloride ions and ammonia molecules as the ligands, draw both isomers of the coordination complex that will exhibit cis/trans isomerism. Platinum (II) forms four coordinate bonds.
