An octahedral complex having the formula [M(dien)(NH3)(OH2)F] has a total of 15 isomers. In the sum formula “dien” represents the tridentate diethylenetriamine ligand, which can adopt meridional or facial coordination modes. Draw structures of 8 possible isomers, clearly showing any pairs of enantiomers. The tridentante ligand may be abbreviated as below for simplicity.
