Mer and fac isomers

The mer-isomer (short for "meridional") has the three chloride ions coordinated in a plane that includes the metal ion. Problem 20P: The conjugate base of 19.28 forms the complex [COL3] which has mer- and fac-isomers, (a) Draw the structures of these isomers, and explain why the labels mer and fac are used, (b) What other type of isomerism does [COL3] exhibit? (c) When a freshly prepared sample of [COL 3] is chromatographed, two fractions, A and B, are collected.

If these three ligands and the metal ion are in one plane, the isomer is said to be meridional, or mer. Click to see full answer Octahedral complexes with three identical ligands oriented about an octahedral center can only exist in mer and fac arrangements.

The ligand L is a bidented ligand. Thus the complex is of the type . For such complexes, the mer-and fac-isomers are possible. Therefore, the isomers of the complex are called the mer-and fac-isomers. Click the Symmetry Operations above to view in 3D [FeCl 3 Br 3] 3-(fac) contains a C 3 axis and 3 σ v planes.
