1. The problem statement, all variables and given/known data Describe, using sketches, how the following ligands can act as both σ-donors and π-acceptors: CN- P(CH3)3 SCN- 2. Relevant equations 3. The attempt at a solution I suspect it has something to do with these ligands having lone pair electrons AND open π* orbitals. How correct is this and if it is wrong then what is the explanation?
