A place in the sun for solutions of [(Ph 3 P) 2 N] 2 [Mn(CN) 6 ] provides—by photochemical degradation—[Mn II (CN) 4 ] 2− ions, the only homoleptic cyanide complex ion that is high spin (structure depicted on the right). Magnetic measurements indicate a high‐spin 6 A 1 ground state ( S =5/2), and the cyanide ligands are virtually entirely σ donors, without significant binding contributions from d–π* back‐bonding.
