Unpaired Electrons and CFSE's with d-orbital splitting
4. (i) How many unpaired electrons are in the following molecules, (ii) is the metal-ion high spin/low spin, and (iii) what are the corresponding CFSEs (in the unit of Delta o. or D q)? For each, you have to draw the d -orbital splitting. Spectrochemical Series might be useful for this. (a) [Cr(H 2 O)6]2^+ (b) [Cr(CN)6]4^- (c) [FeCI4]^- (d) [Fe (CN)6]3^- (e) [Ni(H20)6] 2^+ (f) [Cu(en)2(H2O)2]^2+ (g) on the Mn(III)-ion (derive this for both low spin and high spin metal ions) in [(terpy)Mn^iii(mu-O)2Mnw(terpy)(H2O)2] 3^+
