C--H...O hydrogen-bonding and C--H...pi interactions in 3-(4-fluorophenyl)-1,5,7-trimethyl-1,2,3,4-tetrahydropyrido[2,3-d]pyrimidine-2,4-dione.

In the title compound, C(16)H(14)FN(3)O(2), a diverse set of weak intermolecular C--H...pi, pi-pi and C--H...O interactions link the molecules into sheets. The C--H...O interactions generate centrosymmetric rings with a graph-set motif of R(2)(2)(14) and chains with a C(8) motif.
