Two well-known complex ions containing Ni are [Ni(H2O)6]2+, which is green, and [Ni(en)3]2+, which is purple. Which one of these statements is true?



The crystal field splitting energy (Δ) is greater for [Ni(en)3]2+ than for [Ni(H2O)6]2+.



[Ni(en)3]2+ absorbs energy in the red region of the spectrum.



Both complex ions are diamagnetic.



[Ni(H2O)6]2+ transmits light with wavelengths of approximately 650–700 nm.



The green complex absorbs green light.
