Question

[Fe(CN)_6]^3- has only one unpaired electron, but [Fe(H_2O)_6]^+3 has five. Explain this experimental observation using simple crystal field theory. Diamagnetic complexes of cobalt(III) such as (Co(NH_3)_6]^+3, (Co(en)_3]^+3, and [Co(NO_2)_6]^+3 are orange-yellow. In contrast, the paramagnetic complexes [CoF_6]^+3 and [Co(H_2O)_3F_3] are blue. Explain qualitatively this difference in color. Name the following coordination compounds: [Co(NH_3)_5Cl]Br_2 [Cr(en)_3][FeCl_4]_3 Write the chemical formulas for the following coordination compounds. Potassium tetra chlorine chelate(ll) Tetras(pyridine)platinum(ll) tetra chlorine chelate (ll) (pyridine is a neutral ligand, phenyl is an anionic ligand {C_6H_5^-}) di-mu-carbonyls() chloride (carbonyl is a neutral ligand)
