1,3-Bis(4-methyl-benz-yl)pyrimidine-2,4(1H,3H)-dione.

ABSTRACT

In the title mol-ecule, C(20)H(20)N(2)O(2), the central pyrimidine ring forms dihedral angles of 71.9 (1) and 69.8 (1)° with the two benzene rings. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers. The crystal packing exhibits also π-π inter-actions as indicated by short distances of 3.674 (2) Šbetween the centroids of the pyrimidine rings of neighbouring mol-ecules.
