The crystal structure of 10H-4-methyl-2H-2-oxopyrano[5,6-b]carbazole hydrate was determined by X-ray diffraction. The crystal, 2C16H11NO2·H2O, belongs to space group P21/a with cell dimensions of a = 7.927(6)Å, b = 22.78(1)Å, c = 13.73(1)Å, β = 102.31(2)°. The final R value is 0.061 for 4651 reflections (I > 2.00 σ(I)). There are two independent coumarin molecules (A, B) and one water molecule in an asymmetric unit. Molecules A and B are linked through the N-H…O=C and the C=O…H-O(water)…H-N hydrogen bondings to form a cyclic hetero dimer.
