Question

For each of the following complexes, indicate the (i) metal oxidation state; (ii) number of d electrons present and (iii) coordination geometry. In addition (iv) sketch an appropriate d-orbital splitting diagram and populate it with electrons, explaining your reasoning; (v) determine the spin-only magnetic moment; and (vi) calculate the expected overall orbital stabilization energy, including both the CFSE and pairing energy - you may simply use "P" to represent the latter for any pair of electrons. [Please organize your answers by compound, not property - e.g., group all of the information for (Ru(NH_3)_6]^2+ together rather than listing all of the oxidation states together.] [Ru(NH_3)_6]2+ [Fe(CN)_6]_3 [Ni(OH_2)_6]^2+ [V(en)_3]^3+ (CoCI_4]^2-
