title: 3-(Pyridin-4-yl-thio)-pentane-2,4-dione.
abstract: In the title compound, C(10)H(11)NO(2)S, the acetyl-acetone group crystallizes in the keto form with all the non-hydrogen atoms in the acetyl-acetone group approximately co-planar with a maximum atomic deviation 0.055 (2) Å; the dihedral angle between the acetyl-acetone group and the pyridine ring is 85.90 (6)°. An intra-molecular O-H⋯O hydrogen bond involving the acetyl-acetone group forms a six-membered ring.
