Synthesis, structure characterization and properties of a new oxidovanadium(IV) coordination polymer incorporating bridging (MoO4)2– and (Mo8O26)4– ligands

Abstract Hydrothermal synthesis, crystal structure and properties of a new heterometallic coordination polymer [(VO(terpy)) 4 (MoO ) 2 (Mo 8 O 26 )]·2H ( 1 (terpy = 2,2′;6′,2″-terpyridine) are reported. Compound contains two crystallographically unique vanadium(IV) atoms, bonded to terminal oxido ligand further coordinated terpy ligand. The three N atoms occupy the meridional sites distorted {VN 3 } octahedron. A γ-octamolybdate 4– located on an inversion centre tetraoxidomolybdate 2– function as bridging ligands. μ -bridging tridentate binding leads formation {V Mo 12 4+ cationic unit consisting eight-membered {Mo V ring with protruding oxidovanadium handles. pair units bridged by centrosymmetric ligand, resulting in infinite chain alternating cations anions.
