Ivy League universities have some of the largest university financial endowments in the world, which allows the universities to provide many resources for their academic programs and research endeavors.
Transition metal complexes have colour because the ligands bonding to the central metal atom or ion cause the d-orbitals to have different energies, that is, they are no longe â¦ r degenerate.In octahedral complexes, the dx2-y2 and the dz2 orbitals are higher in energy than the dxy, dxz and the dyz orbitals.ransition metal complexes have colour because the ligands bonding to the central metal atom or ion cause the d-orbitals to have different energies, that is, they are no longe â¦ r degenerate.
The yellow colour of iron(III) in solution is due to species such as [Fe(III)(H2O)5OH]2+, which absorb strongly in the blue-near UV through charge transfer transitions, in which an electron is transferred from a coordinated anion to the reducible central ion.ron(II) ion = green. Iron(III) ion = yellow. Rust (Iron oxide + water)= black or brown. Explain why the rust of iron is not green or yellow, but black or brown. Add your answer. Source.
