One would expect a metal complex with no d-eletron to be colorless as well. However, a few of such complexes are strongly colored, for example, MnO 4-or [Cr 2O7] 2-. The origin of the color in these complexes is not the d-d transitions, rather due to ‘charge transfer’ that we will briefly discuss later.

WebApparently the unstable complex [Fe(S2O3)2]- is formed at the beginning (violet colour) and turns colourless after time. The iron 3+ reduces to iron 2+ and this process can be catalysed but I don't know what reaction pathways the catalyst provides. Help would be appreciated! Catalysts used are 2+ transition metal ions e.g. manganese (ii) chloride

WebIn order to balance the charge of 2 chloride ions (-1 each), we need a +2 charge, so this is the charge of the complex. The type of ligand in this case is just water, a neutral molecule (i.e. its charge = 0). Therefore, if the whole complex has a charge +2 and the ligand has charge 0, it means that the +2 charge comes from the metal: Fe 2+. tisch afaWebDisplay five 250mL beakers with 50mL of Fe(NCS)2+ solution.
