ABSTRACT: In the title compound, C(16)H(14)O(4)·H(2)O, the dihedral angle betwen the benzene rings is 71.4?(6)°. The pyran ring is in a sofa conformation. In the crystal, O-H?O hydrogen bonds connect the components into a two-dimensional network parallel to (010), incorporating C(2) (2)(4) and C(2) (2)(11) chains. In addition, weak C-H?O, C-H?? and ?-? stacking inter-actions [centroid-centroid distance = 3.768?(2)?Å] are present.

Project description:In the title compound, C(16)H(12)O(4), the benzene ring is twisted at an angle of 12.3?(1)° relative to the 4H-chromene skeleton, and an intramolecular O-H?O hydrogen bond occurs. The meth-oxy group is almost coplanar with the benzene ring [1.5?(1)°].

2-(2-Hy-droxy-3-meth-oxy-phen-yl)-6H-perimidin-6-one.

Project description:The mol-ecule of the title perimidine derivative, C(18)H(12)N(2)O(3), is essentially planar, the dihedral angle between the benzene and perimidine rings being 3.25 (5)°. The hy-droxy and meth-oxy groups lie in the plane of the benzene ring to which they are bound [O-C-C-C = 179.96 (11)° and C-O-C-C = -177.96 (12)°]. An intra-molecular O-H⋯N inter-action generates an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of C-H⋯O inter-actions into dimers, which generate S(16) ring motifs. These dimers are arranged into sheets parallel to the ac plane and further stacked down the b axis by π-π inter-actions, with centroid-centroid distances in the range 3.5066 (8)-3.7241 (7) Å.
