Crystal structure of 2,3-dihydronaphto[2,3-b] [1,5] dioxepin

The X-ray single crystal structure Of C13H12O2 compound was determined. It crystallizes in the orthorombic space group P2(1)2(1)2(1) with a = 7.8847(7), b = 9.639(1), c = 13.432(2) Angstrom, Z = 4 and V = 1020.8(3) Angstrom (3). The final R converged to 0.037 for 1763 independent reflexions. The title compound forms layers parallel to (1 0 0) planes and the three dimensional cohesion of the crystal is assumed by Van der Waals interactions. The molecule consists of two six-membered rings (A and B) and a seven-membered ring (C). A and B rings are planar, whereas the C ring has a chair conformation.
