title: 5-Hy-droxy-indan-1-one.
abstract: In the title compound (5HIN), C(9)H(8)O(2), is perfectly planar as all atoms, except the H atoms of both CH(2) groups, lie on a crystallographic mirror plane. In the crystal, mol-ecules are linked by strong inter-molecular O-H⋯O hydrogen bonds, forming an infinite chain along [100], generating a C(8) motif.
