The complex Ni(cyclam)2+(cyclam structure below) is red and diamagnetic when its counterion is the virtually non-bonding (poor Lewis base) ClO4−, but violet and paramagnetic when ClO4−is replaced by the strongly bonding (good Lewis base) SCN−. (a)What is the dnconfiguration of the Ni? (b)Given its diamagnetism, what is the likely structure of the complex in the presence of ClO4−? (c)Sketch out the crystal field splitting pattern that you expect for this structureand compute the crystal field stabilization energy in units of Do. (d)Given its paramagnetism, what is the likely structure of the complex in the presence of SCN−? (e)Sketch out the crystal field splitting pattern that you expect for this structureand compute the crystal field stabilization energy in units of Do.
