Abstract

In the title compound, C(10)H(15)NO(5), the five-membered cyclo-pentane ring has an envelope conformation, with four atoms lying in a plane (mean deviation = 0.0213 Å), while the fifth atom deviates from this plane by 0.626 (2) Å. A three-dimensional structure is formed through N-H⋯O and O-H⋯O hydrogen bonds between the amide and carb-oxy-lic acid groups and both carb-oxy-lic acid and amide O-atom acceptors.
