چکیده
The asymmetric unit of the crystal structure of the title compound, C(16)H(12)N(2)O(2), contains two independent mol-ecules. In each mol-ecule, the two aromatic rings adopt a cis configuration about the central epoxide ring, and are oriented at dihedral angles of 61.5 (5) and 74.4 (5)°with respect to the epoxide ring in one mol-ecule, and 60.1 (5) and 72.1 (5)° in the other one. Inter-molecular classical N-H⋯O and weak C-H⋯O hydrogen bonds are present in the crystal structure.
