Molecular, supramolecular and solution structures of peroxovanadium complexes with ON and O3N donor set ligands: two new types of cationic-anionic peroxovanadium(V) peroxovanadates(V)

Original language description

The complexes, [VO(O-2)(pa)(2)] ClO4 . 3H(2)O ( 1), [VO(O-2)(pa)(2)][ VO(O-2)(2)(pa)] . 3H(2)O (2), [VO(O-2)(pa)(2)][VO(O-2)( ada)] . 2H(2)O ( 3) and [VO(O-2)(pa)(pca)] . H2O ( 4) [pa = picolinamide, ada = carbamoylmethyliminodiacetate( 2-) and pca = 2-pyrazinecarboxylate(1-)], were synthesized. 2 and 3 are new types of peroxovanadium complexes: monoperoxovanadium diperoxovanadate ( 2) and monoperoxovanadium monoperoxovanadate ( 3). The complexes were characterized by chemical analysis and IR spectroscopy, and 1, 3 and 4 also by X-ray analysis. The structure of 1 is disordered, with alternating positions of the oxo and peroxo ligands. The peroxo oxygen atoms, O-p, in 1 are involved in weak hydrogen bonds with water molecules and close intramolecular C- H...O-p bonds [d(H...O-p) similar to 2.0 Angstrom]. The supramolecular structure of 1 is formed by a network of hydrogen bonds and strong attractive intermolecular pi - pi interactions between the pyridine rings. The supramolecular arc
