title: 2-Acetonyl-2-hydroxy-indan-1,3-dione.
abstract: In the title compound, C(12)H(10)O(4), the five-membered ring adopts an envelope conformation, with the Csp(3) atom at the flap [deviation = 0.145 (2) Å]. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.
