Assembly of oximate-bridged Mn6 cluster to a one-dimensional chain

Hexanuclear [MnIII6O2(Hsalaox)6(MeOH)4(MeCO2)2]·4MeOH·2H2O (1) and polymeric [MnIII6O2(Hsalaox)6(MeOH)6(tp)]·12H2O (2) are prepared by the reaction of Mn2+, salicylamidoxime (H3salaox) and corresponding carboxylates (tp2− = terephthalate). Magnetic studies show that both complexes display slow magnetization relaxation.

Hexanuclear [Mn6O2(Hsalaox)6]2+ fragments can form discrete clusters and a terephthalate-bridged 1D chain, which display slow magnetization relaxation.Figure optionsDownload as PowerPoint slideResearch highlights
► Salicylamidoxime as the ligand for polynuclear Mn6 complexes.
► Terephthalic acid as the bridging ligand for polymeric coordination compound.
► Novel 1D complex that contains hexanuclear Mn(III) as nodes.
► Slow relaxation of magnetization for two compounds has been observed.
► No obvious improvements in magnetism by changing Mn6 to 1D.
