title: (E)-1-(1H-Benzotriazol-1-yl 3-oxide)-3-methoxy-but-2-en-1-one.
abstract: The title compound, C(11)H(11)N(3)O(3), crystallizes with two independent mol-ecules of similar geometry in the asymmetric unit. The mol-ecular conformations are stabilized by intra-molecular C-H⋯O hydrogen bonds. The crystal packing consists of wave-like layers parallel to the bc plane formed by inter-molecular C-H⋯O hydrogen-bonding inter-actions involving only one independent mol-ecule.
