(3R,4S)-3,4,8-Trihy-droxy-1,2,3,4-tetra-hydro-naphthalen-1-one monohydrate from Embellisia eureka.


ABSTRACT: In the title hydrate, C(10)H(10)O(4)·H(2)O, the six-membered aliphatic ring that is fused to the benzene ring has a sofa shape, with the hy-droxy group in the 3-position (that represents the sofa back) of the aliphatic ring occupying a quasi-axial position. The hy-droxy group of the aromatic ring is hydrogen-bond donor to the carbonyl O atom; other O-H?O hydrogen bonds link the organic mol-ecules and the water mol-ecules into a three-dimensional network.
