Özet
In the title compound, C24H23FN4O4S center dot 0.25H(2)O, the dihydropyrimidine ring is distinctly non-planar, with the flap C atom deviating by 0.297 (2) angstrom from the least-squares plane. In the crystal, zigzag chains are formed by N-H center dot center dot center dot N hydrogen bonds parallel to [010] and are connected into layers parallel to (100) by O-H center dot center dot center dot O, O-H center dot center dot center dot F, C-H center dot center dot center dot O, C-H center dot center dot center dot F and C-H center dot center dot center dot N hydrogen bonds. Additional C-H center dot center dot center dot O hydrogen bonds connect the layers into a three-dimensional network. A Hirshfeld surface analysis indicates that the most significant contributions to the crystal packing are from H center dot center dot center dot H (42.6%), O center dot center dot center dot H/H center dot center dot center dot O (16.8%) and C center dot center dot center dot H/H center dot center dot center dot C (15.5%) contacts.
