چکیده
The title compound, C(11)H(10)N(2)O, crystallizes with two mol-ecules in the asymmetric unit. The angle at the ether O atom is widened to 118.13 (15)° [117.89 (16)° for the second mol-ecule in the asymmetric unit]; the six-membered rings subtend a dihedral angle of 84.3 (1)° [87.4 (1)° in the second mol-ecule].
