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 decahedral geometry, coordinated by six O atoms from water molecules and one sulfonate O atom. The crystal structure is stabilized by aromatic π–π interactions, with centroid–centroid dista...

| Sumario: | 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 decahedral geometry, coordinated by six O atoms from water molecules and one sulfonate O atom. The crystal structure is stabilized by aromatic π–π interactions, with centroid–centroid distances of 3.765 (5) and 3.896 (5) Å between the phenyl ring and the benzene ring of the chromene unit of neighbouring molecules. In addition, the stacked molecules exhibit inter- and intramolecular O—H⋯O hydrogen bonds, including the uncoordinated water molecules. |
