Original language description

Monoperoxovanadium(V) complexes, [NH3(CH2)(2)NH3][VO(O-2)(ox)(pic)]center dot 2H(2)O (1) and [NH3(CH2)(2)NH3][VO(O-2)(ox)(pca)] (2) [NH3(CH2)(2)NH3 = ethane-1,2-diammonium(2+), ox = oxalate(2-), pic = pyridine-2-carboxylate(1-), pca = pyrazine-2-carboxylate(1-)], were synthesized and characterized by X-ray analysis, IR and Raman spectroscopies. The five equatorial positions of the pentagonal bipyramid around the vanadium atoms are occupied by the eta(2)-peroxo ligand, two oxygen atoms of the ox, and thenitrogen atom of the pic or pca ligands, respectively. The oxo ligand and the oxygen atom of pic or pca are in the axial positions. Networks of X-H...O (X= C, N or O) hydrogen bonds, and pi-pi interactions between aromatic rings in 1 and anion-pi interactions in 2, determine the molecular packings and build up the supramolecular architecture. Three stereochemical rules for occupation of the donor sites in two-heteroligand [VO(O-2)(L-1)(L-2)] complexes (L-1, L-2 are bidentate neutral or
