The hexaaquanickel(II) complex ion, [Ni(H 2 O) 6] 2+ (aq) is green because of the combination of transmitted blue plus. There are two prominent absorption peaks at λ max of 450 nm and λ max at 700 nm- WebComplexes that contain metal ions of d10 electron configuration are usually colorless. Examples are [Cu(PPh 3)4] + and [Zn(H 2O) 6] 2+. 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
