A linear polymer manganese(III) complex; synthesis, crystal and molecular structure and magnetic properties of catena-μ-acetato-[N,N′-O-phenylenebis(salicylideneaminato)]manganese(III)

The X-ray structural analyses reveal that the title complex contains the Mn(saloph) [saloph=N,N′-O-phenylenebis(salicylideneaminato)] moieties bridged by single acetato groups in an anti–anti configuration to form linear polymer chains. Variable temperature magnetic susceptibility measurements (4.7–270 K) show the occurrence of very weak antiferromagnetic interactions between the Mn(III) ions with J=−1.32 cm−1 and D=−0.72 cm−1.
