Novel hybrid inorganic-organic one-dimensional chain systems tailored with monocarboxylic acids
Two novel nanosized hybrid inorganicorganic frameworks, VO(C14H9COO)2, and VO(C10H7COO)2 have been solvothermally synthesized and their structures elucidated using a combination of powder XRD and DFT geometry optimization [1]. They contain one-dimensional chain of corner-sharing tetrahedra in the case of VO(C10H7COO)2, and corner-sharing octahedra for VO(C14H9COO)2 oriented along orthorhombic/monoclinic c-axis, respectively. While VO(C14H9COO)2 exhibits bidentate bridging binding of organic moiety to the metal center, VO(C10H7COO)2 shows monodentate mode as evidenced from DFT and infrared spectroscopy. Both hybrids exhibit fiber-like morphology, consisting of smaller individual single crystals aligned in parallel to the growth direction along the c-axis. They are thermally stable up to 350°C having even more stable impurities containing vanadium in its highest oxidation state. The magnetic properties have been also investigated and indicate antiferromagnetic ordering along the chains characterized by rather low spin exchange parameters.
