The title adduct, C14H13NO·H2O2, consists of (Z)-N-benzyl-idene-1-phenyl-methanamine oxide and hydrogen peroxide mol-ecules in a 1:1 ratio. The organic coformer adopts a skew geometry with an inter-aryl-ring dihedral angle of 81.9 (2)°. In the crystal, the organic and peroxide mol-ecules are linked through both peroxide O-H donor groups to oxide O-atom acceptors, giving one-dimensional chains extending along the b axis. Present also are weak inter-molecular C-H⋯O hydrogen-bonding inter-actions.
Keywords: N-oxide; crystal structure; hydrogen-bond motif; nitrone; peroxosolvate.
