"Web31 Aug 2024 · SCN - is a weak field ligand, which comfortably suggests that it is a π -donor. However, NCS - is relatively high field, and is therefore a π -acceptor - which disagrees with what I've been taught. As sulfur is less electronegative than sulfur, it is higher in energy and therefore contributes more to the anti-bonding orbital. Questions " - Scn or ncs
