The cry stal structure of tert-butyl coumarin-3-carboxylate has been determined . Thi s compound cry stallizes in the triclinic space group P-l with cell parameters a = 5.8038(9) A, b =9.3022(16) A, c = 12.421(2) A, f3 = 97. 107(5t , V = 610.71( 17) A3 D eale = 1.339 mg mי, and Z = 2. The final R valu e is 0.0593 for 2396 reflections . The adjacent molec ules form a cyclic dimer by intermolecular hydrogen bonds of type C=O...H with their carbonyl group and the hydrogen on C(3 ).
