摘要：

K+.C12H8NO3-.H2O, M(r) = 271.32, monoclinic, P2(1)/c, a = 14.388 (2), b = 7.362 (1), c = 11.280 (2) angstrom, beta = 107.79 (2)-degrees, V = 1137.7 (3) angstrom 3, Z = 4, D(x) = 1.58 g cm-3, lambda-(Mo K-alpha) = 0.71069 angstrom, mu = 4.66 cm-1, F(000) = 560, T = 298 K, R = 0.0362 for 1710 unique reflections. The dihedral angle between the phenyl rings is 4-degrees and the dihedral angle between one phenyl group and the adjacent NO2 group is 4-degrees. The anion shows a partial quinoid character and is stacked antiparallel. The potassium cation is eight-fold coordinated through oxygen atoms in the range up to 3.1 angstrom. Hydrogen bridges between water and phenolate oxygens O-H...O with distances of 2.783 (3) and 2.784 (3) angstrom are indicated.
