چکیده
The title compound, C20H18N2O·CH3CN, a perimidine deriv-ative, crystallized as an aceto-nitrile monosolvate. The planes of the naphthalene ring system and the meth-oxy-phenyl ring are oriented almost perpendicular to one another, with a dihedral angle of 87.61 (6)°. The conformation about the C=C bond is E. The hexa-hydro-pyrimidine ring has an envelope conformation, with the methine C atom as the flap. In the crystal, the mol-ecules are linked by N-H⋯N hydrogen bonds involving the aceto-nitrile solvent mol-ecule as acceptor, forming zigzag chains propagating along [100].
