A new polyiodide compound [Ni(bpy)(3)(H2O)(2)]center dot bpy center dot 2H(2)O center dot 2I(3)(-) (1), where bpy is 4,4'-bipyridine, has been synthesized by hydrothermal method. In 1, the adjacent Ni(11) ions are bridged with the bpy ligand to form a 1D chain, which is further extended to be a 3D supramolecular framework by pi-pi interactions. This 3D supramolecular framework is a rare 1D -> 3D interdigitated architecture. Compound 1 has been characterized by X-ray crystallography, elemental analysis, IR, PXRD and TG. The variable-temperature magnetic studies indicate very weak antiferromagnetic interactions in 1. (C) 2019 Elsevier Ltd. All rights reserved.
