Question
The structure of cyanocobalamin, one of the forms of vitamin B12, is given below. Notice that cyanocobalamin is a complex of the transition metal cobalt (Co). Characterize this compound in the following ways: the oxidation state of the cobalt the dn count (that is, the value of n) the total electron count around the metal Two representations of the structure of cyanocobalamin, the first isolated form of vitamin B12, are given above. At left is a Lewis structure; at right is a perspective drawing that shows the position of the two ligands that are above and below the plane defined by the four ring nitrogens.Explanation / Answer
A) The oxidation state of Cobalt is 3.
B)
