WebAug 31, 2024 · SCN-is a weak field ligand, which comfortably suggests that it is a $\pi$-donor. However, NCS-is relatively high field, and is therefore a $\pi$-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. ... $\begingroup ... ipad my232ll/aWebintake of 8 mg SCN/day, for 12 weeks; assuming a reference body weight of 70 kg, the average daily dose was 0.11 mg SCN/kg-day.
