Star formation : Polymeric [Fe 3 (μ 3 ‐O)(μ‐OAc) 6 (H 2 O) 3 ][Fe 3 (μ 3 ‐O)μ‐OAc) 7.5 ] 2 ⋅7 H 2 O is synthesized by linking triangular {Fe 3 (μ 3 ‐O)} clusters through anti‐anti bridging acetate ligands (see picture; red and blue: Fe, orange: O). Spin frustration and long‐range magnetic order coexist in this compound below 4.5 K (see graph).
