AI Article Synopsis
- The crystal structure of pomiferin, a compound with the formula C(25)H(24)O(6), has been elucidated, revealing its molecular arrangement.
- The benzopyranone ring system in pomiferin is almost flat, with a dihedral angle of 40.85 degrees between the phenyl ring and the benzopyranone part.
- The stability of the crystal structure is attributed to a one-dimensional chain of hydrogen bonds involving oxygen atoms, with O...O distances measured between 2.5546 and 2.7999 angstroms.
Article Abstract
The crystal structure of pomiferin, 3-(3,4-dihydroxyphenyl)-5-hydroxy-8,8-dimethyl-6-(3-methylbut-2-enyl)-4H,8H-pyrano[2,3-h]chromen-4-one, C(25)H(24)O(6), has been determined. The benzopyranone ring system is nearly planar and the dihedral angle between the phenyl ring and the benzopyranone moiety is 40.85 (4) degrees. The crystal structure is stabilized by a one-dimensional chain of inter- and intramolecular O-H...O hydrogen bonds, with O...O distances in the range 2.5546 (15)-2.7999 (16) A.
