1. The following coordination complexes are given to you:
[FeCl4]2-, [Cu(H2O)6]2+, [Fe(CN)6]4-, [FeCl4]2-, [Co(NH3)6]3+.
Based on these complexes, use the spectrochemical series to:
(a) determine the configuration (in the form of 𝑡𝑥 𝑒𝑦 or 𝑒𝑥𝑡𝑦,
as appropriate) 2𝑔𝑔 𝑔𝑔 2 (10 marks)
(b) identify the number of unpaired electrons and magnetic
properties of the complexes (5 marks)
(c) compute the ligand-field stabilization energy (LFSE) in Δo.
