title: 4-(2-Hydroxy-benzyl-idene)-3-methyl-isoxazol-5(4H)-one.
abstract: The mol-ecular skeleton of the title mol-ecule, C(11)H(9)NO(3), is approximately planar (r.m.s. deviation = 0.0056 Å); the two rings form a dihedral angle of 6.5 (1)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds involving the H atom of the hydr-oxy group and the N atom of the isoxazole ring link mol-ecules into chains running along the c axis.
