5-(3,4-Dimeth-oxy-benzyl-idene)-1,3-dimethyl-1,3-diazinane-2,4,6-trione.

ABSTRACT: In the title compound, C(15)H(16)N(2)O(5), the dihedral angle between 1,3-diazinane and benzene rings is only 4.27?(1)°. The essentially planar mol-ecular structure is characterized by a short intra-molecular C-H?O separation and by an exceptionally large bond angle of 138.25?(14)° at the bridging methine C atom. The meth-oxy groups deviate somewhat from the plane of the benzene ring, with C-C-O-C torsion angles of -15.6?(1) and 9.17?(6)°. In the crystal, mol-ecules form centrosymmetric dimers via donor-acceptor ?-? inter-actions, with a centroid-centroid distance of 3.401?(1)?Å.
