Li HJ, Zhou DL, Xu TJ, Lam CK, Lan WJ - Acta Crystallogr Sect E Struct Rep Online (2012)

Bottom Line: THE TITLE COMPOUND [SYSTEMATIC NAME: 5,6,7-trimeth-oxy-2-(7-meth-oxy-1,3-dihydro-2-benzofuran-5-yl)-4H-chromen-4-one monohydrate], C(20)H(18)O(8)·H(2)O, was isolated from the popular Chinese medicinal plant Entada phaseoloides.In the crystal, inversion-related mol-ecules are joined by pairs of weak C-H⋯O hydrogen bonds.The dimers are further inter-connected by a bridging water mol-ecule via weak C-H⋯O(water) and pairs of (O-H)(water)⋯O hydrogen bonds into a linear tape running parallel to the b axis.

ABSTRACT
THE TITLE COMPOUND [SYSTEMATIC NAME: 5,6,7-trimeth-oxy-2-(7-meth-oxy-1,3-dihydro-2-benzofuran-5-yl)-4H-chromen-4-one monohydrate], C(20)H(18)O(8)·H(2)O, was isolated from the popular Chinese medicinal plant Entada phaseoloides. In the crystal, inversion-related mol-ecules are joined by pairs of weak C-H⋯O hydrogen bonds. The dimers are further inter-connected by a bridging water mol-ecule via weak C-H⋯O(water) and pairs of (O-H)(water)⋯O hydrogen bonds into a linear tape running parallel to the b axis.
