摘要

The X-ray crystal structure of 7-hydroxyflavone monohydrate, C14H10O3. H2O, is determined. The compound crystallizes in the monoclinic space group, P2(1) with a = 3.801(3), b = 19.665(4), c = 16. 039(6), beta = 93.69(3)degrees, and mu = 0.68 mm(-1) for Z = 4. The phenyl ring of the flavone moiety is rotated 18.6(1)degrees out of the penzopyran plane, which is a typical value for flavones. In the crystal lattice, there are wide channels which are lined mainly by C-H groups. The water molecules enclosed in these channels are severely disordered. [References: 8]
