title: Dimethyl cis-4-hydroxy-methyl-piperidine-2,6-dicarboxyl-ate.
abstract: The heterocyclic core of the title compound, C(10)H(17)NO(5), adopts a chair conformation with its three C substituents positioned equatorially. In the crystal, inter-molecular O-H⋯N hydrogen bonds between neighbouring mol-ecules lead to chains along b. These chains are connected by hydro-phobic inter-actions, forming infinite layers and N-H⋯O=C contacts between mol-ecules of adjacent layers give rise to a three-dimensional structure.
