Question:

(a) Which of the following octahedral complexes are chiral: cis-[CoCl2(en)2]+, [Cr(ox)3]3−, trans-[PtCl2(en)2]2+, [Ni(phen)3]2+, [RuBr4(phen)], cis-[RuCl(py)(phen)2]+?

(b) The solution 31P NMR spectrum of a mixture of isomers of the square planar complex [Pd(SCN)2(Ph2PCH2PPh2)] shows one broad signal at 298 K. At 228 K, two singlets and two doublets (J = 82 Hz) are observed and the relative integrals of these signals are solvent dependent. Draw the structures of the possible isomers of [Pd(SCN)2(Ph2PCH2PPh2)] and rationalize the NMR spectroscopic data.
