6-Oxo-1,6-dihydropyridazine-3-carbaldehyde monohydrate
In the title hydrate, C(5)H(4)N(2)O(2)·H(2)O, the pyridazine ring is essentially planar, with an r.m.s. deviation of 0.0025 Å. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a one-dimensional chain.

In the title compound, C(11)H(8)O(3), the benzopyran-4-one or chromone ring system is almost planar, with a maximum deviation of 0.045 (2) Å. The crystal structure is stablized by π-π inter-actions between the benzene and pyran rings of inversion-related mol-ecules stacked along the b axis, with a centroid-centroid distance of 3.5463 (12) Å

In the title compound, C10H5IO3, an iodinated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0259 Å), with the largest deviation from the least-squares plane [0.056 (5) Å] being found for the formyl O atom. In the crystal, mol-ecules are linked through I⋯O halogen bonds [I⋯O = 3.245 (4) Å, C-I⋯O = 165.95 (13) and C=O⋯I = 169.7 (4)°] along [101]. The...

In the title compound, C11H7ClO3, a chlorinated and methyl-ated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0670 Å), with the largest deviation from the least-squares plane [0.2349 (17) Å] being for the pyran carbonyl O atom. In the crystal, mol-ecules are linked through π-π stacking inter-actions along the a axis [centroid-centroid distance betw...
متن کامل6-Chloro-7-fluoro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C10H4ClFO3, a chlorinated and fluorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0336 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.062 (2) Å] being for a benzene-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions [centroid-centroid distance between the benzene and py...
