In a fac isomer, any two identical ligands are adjacent or cis to each other. If these three ligands and the metal ion are in one plane, the isomer is said to be meridional, .

Jun 05, · In fact, they are isomers, one is facial and the other one is meridional. The Ho−O distances are from to Å, and the average Ho−O distance is Å. The bond angles related to amide groups, O1 C1 N1, O2 C7 N2 and O3 C13 N3 are , and °, respectively, which are smaller than Ho-NtBA (I).Cited by: 1. Facial (fac) and meridional (mer) isomerism, a type of geometrical isomerism, is shown by octahedral complexes having M a 3 b 3 general formula. (Where, M is central metal and a and b are monodentrate ligands). Hence, [C o (N H 3) 3 C l 3 ] exhibits fac-mer isomerism as.
Facial and Meridional Isomers:In facial isomers three identical donor atoms lie on the corners of a triangular face and in meridional isomer three identical donor atoms lie on the corners of the plane bisecting the complex. There are four types of complexes which exist in fac- . If three donor atoms of the same ligands occupy adjacent positions at the corners of an octahedral face, we have the facial (fac) isomer. When the positions are around the meridian of the octahedron, we get the meridional (mer) isomer Facial Isomers: A set of three ligands (similar) arranged on .
