Author(s): Mehtab Parveen,*, Sayed Hasan Mehdi, Raza Murad Ghalib,Mahboob Alam and Raghavaiah Pallepogu

The title compound, 7-benzoyloxycoumarin, C16H10O4, crystallizes into monoclinic space group P2(1) with unit-cell parameter: a = 3.8479(7), b = 27.693(5), c = 5.7259(10) Aο. Z = 2. The crystal structure was solved by direct methods and refined to a final R-value of 0.0535 for 3295 observed reflection. The benzoyloxy ring present on 7- position was found to be almost coplanar with coumarin. The structure is stabilized by vander Waal’s interactions. The structure of this compound was also established by 1H NMR spectrum of its solution in CDCl3.
