To which of Cu(II) and Zn(II) is Ni(II) most similar regarding formation of hydroxo– and ammine–complexes? Explain.
Homework Answers
Ni(II) is very similar to Cu(II) , regarding formation of hydroxo and Ammine Complexes. Because, both Cu(II) and Ni(II) form Octahedral Hydroxo and Ammine complexes, whereas Zn(II) always form Tetrahedral Complexes, due to 0 CFSE. Both Cu(II) and Ni(II) Ammine and Hydroxo Complexes are highly Coloured, whereas Zn(II) Complexes are Colourless.

Cobalt(II) can substitute for Zn(II) in carbonic anhydrase and other proteins in which the metal ion acts as a Lewis Acid. The coordination chemistry of Co2+ is very similar to that of Zn2+, and the two ions have almost identical radii. Cobalt ion is an excellent structural and functional model for studies of a protein’s zinc binding sites. The advantage of Co(II)–substituted proteins is that they exhibit d → d transitions in the visible region of the electromagnetic spectrum, as...
