(Z)-1-Ethyl-3-(4-chlorobenzylidene)-1,2,3,5-tetrahydroimidazo[2,1-b]quinazoline-2,5-dione

Abstract

The central part of the title molecule, C19H14C1N302, The main skeleton of the molecule (three condensed 7r-electron rings inclined slightly towards one another) and the phenyl ring have a Z configuration with torsion angle N1---C5---C6--C16 = -8.5 (9) °. Thus, as a result of steric hindrance, the imidazo-quinazolinedione skeleton and the phenyl ring are not coplanar, and form a dihedral angle of 48.1 (1)°.
