Synthesis and Crystal Structure of an Oxovanadium(IV) Complex Containing L-Phenylalanine Schiff Base and 1,10-Phenanthroline

Abstract:

A new oxovanadium (IV) complex, [VO(o-van-phe)(phen)] (1) (o-van-phe = Schiff base derived from o-vanillin and L-phenylalanine, phen =1,10-phenanthroline), has been synthesized and characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. The results show that complex 1 belongs to triclinic crystal system, with P-1 space group, a=10.646(2) Å, b=11.089(3) Å, c=14.143(4) Å, α=67.374(4)°, β=79.685(4)°, γ=89.711(4)°, Z=2, V=1512.5(7) ų, Dc =1.195 mg·m^–3, μ=0.366 mm^–1, F(000)=562. In the molecular structure, the V(IV) ion is six coordinated to form a distorted octahedral geometry. In the crystal, a dimer is formed by intermolecular hydrogen bonding and π–π stacking interactions.
