Choose the most likely pattern for the crystal field diagram for
the complex
trans–[Ni(NH3)2(CN)4]2–
where CN– produces a much stronger crystal field than
does NH3.?
From the answer the pattern show it is a square planer. Could
anyone explain it? why is not octahedral?

For every first row 4-coordinate complexes from Sc2+ to Zn2+
what would the expected room temperature magnetic moment be if each
were tetrahedral? Square planar? How do these compare for
6-coordinate, octahedral complexes of both?
