• Three new Strandberg type complexes were synthesized and characterized.
• In the crystal structure, spiral chain is assembled via intermolecular interactions.
• Temperature/magnetic-induced 2D-IR COS reveal relative structure properties.
Three Strandberg type molybdophenylphosphonate complexes with the formular {[Cu(2,2′-bpy)2]2[(C6H5P)2Mo5O21]}·H2O (1), [Ni(2,2′-bpy)3]2[(C6H5P)2Mo5O21]·2H2O (2) and {[Ni(2,2′-bpy)2]2[(C6H5P)2Mo5O21]·H2O}·2H2O (3) (bpy = bipyridine) have been synthesized under hydrothermal condition and structurally determined by single-crystal X-ray diffraction. The cations and the anionic clusters in three compounds are linked via strong covalent bonds or the hydrogen bonds. Intermolecular interaction makes the building blocks construct supramolecular structure and assembles a spiral chain in compound 2. The interaction also plays an important role in the stabilization of the molecular aggregate. The obtained compounds were characterized by various means containing elemental analysis, PXRD, IR, TGA and thermal infrared spectra. In order to investigated the structural characteristics of intermolecular interaction and thermal stability or magnetic sensitivity of the compounds, 2D-IR correlation spectra (2D-IR COS) under thermal/magnetic perturbation were carried out. And the magnetic property was studied as well.
Three Strandberg type molybdophenylphosphonates were hydrothermally synthesized. The 2D-IR COS and thermogravimetry were applied to exploit the molecular interaction induced by thermal/magnetic perturbation. The magnetic property was studied as well.Figure optionsDownload as PowerPoint slide
