Crystal structure of (E)-2-(4-meth­oxy­styr­yl)-23-di­hydro-1H-perimidine aceto­nitrile monosolvate

摘要

The title compound, C20H18N2O·CH3CN, a perimidine deriv­ative, crystallized as an aceto­nitrile monosolvate. The planes of the naphthalene ring system and the meth­oxy­phenyl 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 hexa­hydro­pyrimidine ring has an envelope conformation, with the methine C atom as the flap. In the crystal, the mol­ecules are linked by N—H⋯N hydrogen bonds involving the aceto­nitrile solvent mol­ecule as acceptor, forming zigzag chains propagating along [100].
