The title compound, N-hydroxy-N-pivaloyl-glycine isopropylamide, C10H2
0N2O3, crystallizes with two independent molecules adopting two differ
ent extended conformations. The planar trans hydroxamide group has sim
ilar dimensions to the standard peptide bond. The hydroxamide N-OH gro
up, which is roughly perpendicular to the hydroxamide plane, is engage
d in a short contact with the glycine carbonyl group.
