(±)-3-Oxocyclo­pentanecarboxylic acid: the smallest keto acid known to aggregate by catemeric hydrogen bonding

The title compound, C6H8O3, is the smallest keto acid yet found to aggregate in the solid as acid‐to‐ketone hydrogen‐bonded catemers. Four translational chains pass through the cell in the a direction [O⋯O = 2.6915 (14) Å and O—H⋯O = 166°]. Two inter­molecular C—H⋯O close contacts exist, involving b...

Summary:The title compound, C6H8O3, is the smallest keto acid yet found to aggregate in the solid as acid‐to‐ketone hydrogen‐bonded catemers. Four translational chains pass through the cell in the a direction [O⋯O = 2.6915 (14) Å and O—H⋯O = 166°]. Two inter­molecular C—H⋯O close contacts exist, involving both carbonyl functions.
