  • Original language description

    Osajin [systematic name: 5-hydroxy-3-(3-hydroxyphenyl)-8,8-dimethyl-6-(3-methylbut-2-enyl)-4H,8H-pyrano[2,3-h]chromen-4-one, C25H24O5, crystallizes with two independent molecules in the asymmetric unit. The benzopyranone ring system is nearly planar in both molecules and they differ significantly only in the orientation of the benzene rings, which are rotated by 56.27 (7) and 44.16 (7)deg. with respect to the benzopyranone systems. In the crystal structure, intermolecular O-H...O hydrogen bonds link themolecules into dimers.

    Osajin [systematické jméno: 5-hydroxy-3-(3-hydroxyphenyl)-8,8-dimethyl-6-(3-methylbut-2-enyl)-4H,8H-pyrano[2,3-h]chromen-4-one, C25H24O5, krystaluje se dvěma nezávislými molekulami v asym. buňce. Aromatické části obou molekul jsou téměř planární, a obě molekuly se navzájem liší pouze orientací benzen. kruhů, které svírají s benzopyranon. částí molekuly úhly 56.27(7) a 44.16(7) deg. V krystalech jsou molekuly spojeny mezimolekulárními O-H...O vodík. vazbami do formy dimerů.
