Question

Square-planar Pd(II) binds two molecules of enantiopure L = (R)-H₂NCH(CH₃)CH₂NH₂. Label its donor ends A (beside CHCH₃) and B (beside CH₂). Ignoring ring conformations, let g be the number of donor-arrangement forms and u the number of unpaired electrons in each. Which is correct?

TestHub · Accepted Answer

Two adjacent AB chelates on a square give cis-A/A and trans-A/A arrangements, hence g = 2. Square-planar Pd(II) is paired d⁸, u = 0. Each ion retains two R ligand centres; reflection gives S centres. A planar donor set does not make the complete ligand framework achiral.
