a. In the absorption spectrum of the complex ion Cr(NCS)63, there is a band corresponding to the absorption of a photon of light with an energy of 1.75 104 cm-1. Given 1 cm1 = 1.986 1023 J, what is the wavelength of this photon? b. The CrNC bond angle in Cr(NCS)63 is predicted to be 180. What is the hybridization of the N atom in the Ncs- ligand when a Lewis acid-base reaction occurs between Cr3+ and NCs- that would give a 180 CrNC bond angle? Cr(NCS)63 undergoes substitution by ethylenediamine (en) according to the equation Cr(NCS)63+2enCr(NCS)2(en)2++4NCS Does Cr(NCS)2(en)2+ exhibit geometric isomerism? Does Cr(NCS)2(en)2+ exhibit optical isomerism?
The acetylacetone ion forms very stable complexes with many metallic ions. It acts as a bidentate ligand, coordi- nating to the metal at two adjacent positions. Suppose that one of the CH3 groups of the ligand is replaced by a CF; group, as shown here: н Trifluoromethyl acetylacetonate CF-Ç (ffac) C-CH3 :Ö: :0: Sketch all possible isomers for the complex with three tfac ligands on cobalt(III).

6.) a.) In the series of Werner complexes (after the German-Swiss chemist) [CoX(NH3)5]* with X = I', Cl', NH3, there is a color variation from purple (I'), through pink (CI') to yellow (NH3). Explain this observation. b.) The same transition metal ion can provide a different color to different host lattices. Red ruby consists of an Al203 corundum host structure where Cr3+ dopants occupy octahedral sites surrounded by 02. In green emeralds, however, Cr3+ acts as a dopant of the beryl (Be3Al2(SiO3)6) host, wherein it occupies octahedral sites, surrounded by six silicate ions. With this information, determine whether the silicate anions impose a stronger or weaker ligand field compared to 02. Explain your reasoning.
