How does one solve this question can someone pls explain how there are 6 ligands?
Vitamin B12 is an essential nutrient containing Cobalt
(Co). Cyanocobalamin, shown at right, is one form of B12 in
which the cobalt center has a cyanide ligand. In addition, the
cobalt is coordinated by a ring structure, whose long tail (at
bottom) loops underneath and makes a final stabilizing
coordination.
