Polybis(1-methyl-2-thioimidazolate)iron(II): Crystal Structure and Magnetic Properties of a One-Dimensional Material Exhibiting Ferromagnetic Ordering below 8 K. The title compound has a rodlike 1-D structure in which iron ions are double bridged by 1-methyl-2-thioimidazolate ligands and the metal chromophores alternate along the chain between FeS4 and FeN4. Antiferromagnetic intrachain coupling with spin canting generates residual spin on the chains that undergo long-range ferromagnetic order below 8 K.
