An Oximate-Free Ferromagnetically Coupled Triangular [MnIII3(μ3-O)]7+ Core

The Schiff-base ligand H 2 L, N-(2-hydroxymethylphenyl)salicylideneimine yields a trimanganese(III) complex, [L 3 Mn III 3 -(μ 3 -O)(MeOH) 3 ]PF 6 (1), in which monoatomic alkoxo-bridging is present along the edges of the Mn 3 -triangle containing d 4 high-spin manganese(III) centers, which are ferromagnetically coupled resulting in an S t = 6 spin ground state for 1.
