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(aza-nedi-yl)]bis-(methyl-ene)}diphenolato)oxidovanadium(V)],[V2(C16H18N2O2)2O3] (1), was crystallized by slow evaporation from an ethanol solution. The μ-oxo dimer crystallizes in the monoclinic space group C2/c where the salan ligand 1a coordinates to the vanadium center in a κ2 N,κ2 O fashion, forming a distorted octa-hedral geometry. The bridging oxo ligand lies on a crystallographic twofold axis. The unit cell consists of four mol-ecules of 1 that are linked by C-H⋯·πarene inter-actions as well as intra-molecular hydrogen bonding.
