The CN ligand can act as a o donor and a π acceptor. The o donor orbital is anti- bonding with respect to the C-N bond. Given that the v(CN) stretching frequency in the IR spectrum of [Pt(CN)4]2 is 2170 cm¹ while free CN-exhibits v(CN) at 2080 cm-¹, which property, a donation or π acceptance dominates in this complex? Provide a clear explanation of your reasoning.
