The color and wavelength of the absorption maximum for [Ni(H₂O)₆]²⁺, [Ni(NH₃)₆]²⁺, and [Ni(en)₃]²⁺ are given in Figure 23.30. The absorption maximum for the [Ni(bipy)₃]²⁺ ion occurs at about 520 nm.

(a) What color would you expect for the [Ni(bipy)₃]²⁺ ion?

(b) Based on these data, where would you put bipy in the spectrochemical series?
