Crystal structure of a μ-oxo vanadium(V) dimer coordinated by a salan ligand

A μ -oxo vanadium(V) dimeric complex, μ-oxido-bis[(2,2′-{[ethane-1,2-diylbis(azanediyl)]bis(methylene)}diphenolato)oxidovanadium(V)], [V 2 (C 16 H 18 N 2 O 2 ) 2 O 3 ] ( 1 ), was crystallized by slow evaporation from an ethanol solution. The μ -oxo dimer crystallizes in the monoclinic space group C 2/ c where the salan ligand 1a coordinates to the vanadium center in a κ 2 N ,κ 2 O fashion, forming a distorted octahedral geometry. The bridging oxo ligand lies on a crystallographic twofold axis. The unit cell consists of four molecules of 1 that are linked by C—H...·π arene interactions as well as intramolecular hydrogen bonding.
