A triclinic polymorph of (E)-2-(1-hy­droxy-3-phenyl­prop-2-en-1-yl­idene)-4,5-dimeth­oxy­cyclo­pent-4-ene-1,3-dione

The title compound, C(16)H(14)O(5), is a triclinic polymorph of a previously reported monoclinic structure [Hosseinzadeh et al. (2011 ▶). Acta Cryst. E67, o1544]. The mol­ecule is roughly planar, the r.m.s. deviation from the least-squares plane of all non-H atoms being 0.092 Å. In the crystal, adja...

description The title compound, C(16)H(14)O(5), is a triclinic polymorph of a previously reported monoclinic structure [Hosseinzadeh et al. (2011 ▶). Acta Cryst. E67, o1544]. The mol­ecule is roughly planar, the r.m.s. deviation from the least-squares plane of all non-H atoms being 0.092 Å. In the crystal, adjacent mol­ecules are linked through C—H⋯O hydrogen bonds into an infinite two-dimensional network parallel to (011). The layers are further connected via C—H⋯π inter­actions, forming a three-dimensional structure. Intra­molecular O—H⋯O and C—H⋯O hydrogen bonds are also observed.
