title: 4-Hy-droxy-indan-1-one.
abstract: The mol-ecule of the title compound, C(9)H(8)O(2), is essentially planar except for the methyl-ene H atoms [maximum deviation = 0.028 (1) Å]. In the crystal, the mol-ecules are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions into chains along [110] and [1-10].
