title: cis-3-(tert-Butoxy-carbonyl-amino)cyclo-hexa-necarboxylic acid.
abstract: The title compound, C(12)H(21)NO(4), a γ-aminobutyric acid derivative, crystallizes with two mol-ecules in the asymmetric unit. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming a strand. An intramolecular N-H⋯O hydrogen bond is also observed.
