Question

Determine the configuration (in the form t2g

meg

n or emt2

n, as appropriate), the

number

of unpaired electrons, and the ligand field stabilization energy as a muiple of

Δo or ΔT for each of the following complexes using the spectrochemical series to decide,

where relevant, which are likely to be strong‐field and which weak‐field.

(a)[Co(NH3)6]3+; (b) [Fe(OH2)6]2+; (c) [Fe(CN)6]3–; (d) [Cr(NH3)6]3+; (e) [W(CO)6]; (f)

[FeCl4]2– and (g) [Ni(CO)4].
