Coordination Chemistry

It is a part of chemistry, in which the study of compounds that have central atoms surrounded by molecules or ions, known as ligand, is known as coordination chemistry.

Question

The electron transfer reactions of [Co(CN),(OH2)]* with both [Co(NH3)s(SCN)]2* and
[Co(NH3),(NCS)** yield [Co(CN)s(SCN)]³ as one of the products of the reaction. The
bridged intermediate can be formed by attack at two different locations on the SCN-
ligand.
The S-bonded linkage isomer of [Co(NH3);(SCN)]2* has a Co-S-C bond angle of
approximately 105°, while the N-bonded linkage isomer has a Co-N-C bond angle of
180°.
1. Please determine each of the following for the starting complexes
([Co(CN).(OH2)* and [Co(NH3)s(SCN)]²*):
a. the MLXZ classification,
b. the equivalent neutral classification (ENC),
c. the ligand bond number (LBN),
d. the valence number (VN),
e. the metal dn count, and
f. the total electron count (TEC).
2. For the following redox reaction, please indicate whether the metal center is inert
or labile towards ligand substitution.
[Co(CN):(OH2)]* + [Co(NH3)s(NCS)]r* = [Co(CN):(SCN)]* + [Co(OH2);J²*
3. Explain why, in the products of this reaction, one of the cobalt centers has lost all
of the ammonia ligands initially attached to it.
4. Draw the Lewis structure for the SCN ligand and explain the two different ways
that it can function as a bridging ligand.
5. In the redox reactions between [Co(CN)s(OH2)]³ and both linkage isomers of
[Co(NH3)s(SCN)]1**, [Co(CN),(SCN)]³- is one of the products formed. Please draw
the two different bridged intermediates (one that results from the reaction of each
linkage isomer) that lead to the single S-bonded product.
6. In the redox reaction between [Co(NH3)5(SCN)]²* and [Cr(OH2)eJ²*, both remote
and adjacent attack on the SCN ligand can occur, resulting in the formation of
[Cr(OH2)s(NCS)]2+ and [Cr(OH2),(SCN)]²*, respectively. When [Co(NH3)s(NCS)]²*
is used, only [Cr(OH,)s(SCN)]²* is formed. Please explain these results.
