| Abstract | The asymmetric unit of the title compound, C(8)H(12)O(3), consists of a single conformational enanti-omer, which aggregates in the catemeric acid-to-ketone hydrogen-bonding mode [O⋯O = 2.682 (4) Å and O-H⋯O = 172 (6)°]. Four hydrogen-bonding chains of translationally related mol-ecules pass through the cell orthogonal to the 4(3) screw axis along c, alternating in the 110 and the 10 direction, with alignment with respect to this axis of + + - -. Successive chains are rotated by 90° around the c axis. One C-H⋯O=C close contact, involving the carboxyl group, exists. |
