The absolute configuration of the title compound, C(18)H(24)O(5)·H(2)O, was not been determined by anomalous-dispersion effects, but has been assigned by reference to an unchanging chiral centre in the synthetic procedure. Intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, O-H⋯O hydrogen bonds link the main mol-ecules and the water mol-ecules, forming an...

THE TITLE COMPOUND (SYSTEMATIC NAME 5,7-dihydr-oxy-3,6,8-trimeth-oxy-4H-chromen-4-one), C(18)H(16)O(7), is a flavone that was isolated from Ainsliaea henryi. There are two mol-ecules in the asymmetric unit, one of which has a disordered meth-oxy group [occupancy ratio 0.681 (9):0.319 (9)]. Both mol-ecules have an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are linked into O-...

In the mol-ecule of the title compound, C(18)H(22)N(2)O(3), the dihydro-pyrimidinone ring adopts an envelope conformation. The dihedral angle between the phenyl ring and the mean plane through the enamine fragment is 86.04 (7)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, inter-molecular N-H⋯O hydrogen bonds link pairs of mol-ecules into ...

The asymmetric unit of the title mononuclear compound, [Ag(C(6)H(5)ClNO(3)S)(C(18)H(15)P)(2)], contains four independent mol-ecules. In each of the mol-ecules, the Ag(I) cation is three-coordinated by two triphenyl-phosphine ligands, and one N atom from a 2-amino-5-chloro-benzene-sulfonate anion. The mol-ecules are linked into a one-dimensional supra-molecular structure by N-H⋯O hydrogen bonds.

The asymmetric unit of the title compound, C(13)H(11)ClN(2), contains two geometrically distinct mol-ecules; one mol-ecule is close to planar [dihedral angle between the aromatic rings = 2.44 (18)°] and the other is twisted about the linking hydrazide group [dihedral angle = 14.08 (19)°]. In the crystal, the N-H groups do not form hydrogen bonds and the mol-ecules are linked by weak C-H⋯π inter...

The asymmetric unit of title compound, C(19)H(22)INO, contains two independent mol-ecules. Classical intra-molecular O-H⋯N hydrogen bonds stabilize the mol-ecular structures. The crystal structure is stabilized by weak inter-molecular C-H⋯π and π-π [centroid-centroid = 3.8622 (18) Å] inter-actions. In both mol-ecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = ...
