Hexaaqua(5,7-dihydroxy-4-oxo-2-phenyl-4H-chromene-8-sulfonato)calcium(II) 5,7-dihydroxy-4-oxo-2-phenyl-4H-chromene-8-sulfonate trihydrate
In the title compound, [Ca(C(15)H(9)O(7)S)(H(2)O)(6)](C(15)H(9)O(7)S)·3H(2)O, the Ca centre has a distorted deca-hedral geometry, coordinated by six O atoms from water mol-ecules and one sulfonate O atom. The crystal structure is stabilized by aromatic π-π inter-actions, with centroid-centroid distances of 3.765 (5) and 3.896 (5) Å between the phenyl ring and the benzene ring of the chromene un...
متن کامل3-Methyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid
In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol-ecules in the crystal structure is governed by C-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
متن کاملPoly[(μ-5,7-dihydroxy-4-oxo-2-phenyl-4H-chromene-8-sulfonato)potassium(I)]
In the polymeric title compound, [K(C(15)H(9)O(7)S)](n), the potassium cation is five-coordinated by four sulfonate O atoms and one carbonyl O atom. Two intra-molecular O-H⋯O hydrogen bonds stabilize the conformation of the anion. The polymeric three-dimensional supra-molecular architecture is formed via coordination inter-actions and π-π stacking inter-actions involving centrosymmetrically rel...
متن کامل6-Bromo-3-hydroxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid dimethylformamide disolvate
In the title compound, C(16)H(9)BrO(5)·2C(3)H(7)NO, the chromene ring system is essentially planar. The two dimethyl-formamide solvent mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds to the 6-bromo-3-hydr-oxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid molecules.
متن کامل8-Chloro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C10H5ClO3, a chlorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. deviation = 0.032 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.0598 (14) Å] being for a pyran-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions along the b axis [shortest centroid-centroid distance between ...
