3-Hydroxy-4-(3-hydroxyphenyl)-2-quinolone monohydrate
In the title compound, also known as viridicatol monohydrate, C(15)H(11)NO(3)·H(2)O, the dihedral angle between the benzene ring and quinoline ring system is 64.76 (5)°. An intra-molecular O-H⋯O hydrogen bond occurs. The crystal structure is stabilized by classical inter-molecular N-H⋯O and O-H⋯O hydrogen bonds and weak π-π inter-actions with a centroid-centroid distance of 3.8158 (10) Å.

The structure of the title compound, C(15)H(21)N(3)O(6)·H(2)O, is of inter-est with respect to assumed anti-cancer activity. The title mol-ecules are linked through inter-molecular O-H⋯O hydrogen-bonded chains along the a axis. These chains are connected by inter-molecular N-H⋯O hydrogen bonds through the crystallographic screw axis along [010], forming layers, which are stabilized by other N-H...

In the crystal structure of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-)·H(2)O, the water mol-ecule acts as an acceptor of bifurcated N-H⋯O hydrogen bonds from the pyridinium H atom and one H atom of the 2-amino group, forming an R(2) (1)(6) ring. The 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions self-assemble via O-H⋯O hydrogen bonds, leading to supra-molecular chains along the a axis. T...
