- W2092549466 abstract "Bis(hydroxamido)hydroxooxovanadate has been found to undergo favourable condensation reactions with simple peptides such as glycylglycine, glycylglycylglycine, or glycyltyrosine to afford, in each case, three products in the approximate ratio 1:3.5:0.2. The three products had the same ligand stoichiometry and, in the case of glycylglycine, an overall formation constant of 3.3 × 10 3 M −1 for the addition of GlyGly to bis(hydroxamido)vanadate. The 51 V chemical shift range of the products (close to −850 ppm) overlaps that of the starting complexes and the products may well have a coordination geometry similar to the parent complexes. The chemical shifts observed for these materials are in the range of chemical shifts observed for peroxovanadium complexes. A crystalline monomeric complex with a single glycylglycinato ligand was obtained and its crystal structure determined. The complex is zwitterionic and has a pentagonal bipyramidal coordination at vanadium with the glycine-NH 2 functionality coordinated in the plane of the two hydroxyalamine ligands and the amido carbonyl oxygen in the apical position. Some comparisons with peroxovanadium complexes are drawn. Crystal structure of V(O)(ONH 2 ) 2 (GlyGly)•H 2 O: monoclinic, space group Cc; Z = 4; a = 9.1340(9) Å; b = 16.3355(15) Å; c = 7.1149(6) Å; β(°) = 103.020(7); V = 1034.31 Å 3 ; T = 295 K; R F = 0.21 for 2513 data (I 0 ≥ 2.5σ(I 0 )) and 197 variables. Keywords: vanadate, hydroxylamine, N-methylhydroxylamine, oxobis(hydroxamido)glycylglycinatovanadium(V), peptide complex, glycylglycine, 51 V NMR, crystal structure." @default.
