영어

The crystal structure of the potential active methyl-3-phenyl-3H-chromeno[4,3-c]isoxazole-3a(4H)- carboxylate (C18H15NO4) has been determined from single crystal X-ray diffraction data. In the title compound crystallizes in the orthorombic space group P212121 with unit cell dimension a=9.8320 (17) Å, b=9.9890 (18) Å and c= 15.588 (3)Å [α=90°, β= 90o and γ= 90o]. In the structure chromene, isoxazole and carboxylate are almost coplanar each other. All geometrical parameters revelled that chromene ring of pyran ring adopt sofa conformation. The crystal packing is stabilized by intermolecular C-H...O and C-H...N hydrogen bond interaction.
